BFont: remove default values from ambiguous method

Noticed by Joachim Mairböck after I hastily merged change 7402.

Also add named variation instance selection for fonts loaded from memory
areas like there already is for files.

app_server FontManager: load all fonts and named-variants from a file

BFont::LoadFont can now use an index (0-based) and an optional named-instance (1-based)
to select the font variant from a file.
BFont::LoadFont can also use an index when loading from memory.

BFont: allow loading of user fonts from disk or memory

This patch adds an API call to BFont, called LoadFont, that
takes a string path to a font file. The user fonts are managed
via a new class called AppFontManager that inherits from the base
class FontManagerBase but adds the methods to add and remove user
fonts from disk or memory. There is also a new method called UnloadFont
to remove a user font, but on exit of an app all user fonts should be
automatically cleaned up.

Global/system fonts are managed by the GlobalFontManager, which is
a new class that also inherits from the base class FontManagerBase,
replacing the old "FontManager" class.

A maximum of 128 user fonts may be loaded, and memory fonts
may not exceed 20MB.

There's also an overloaded version of LoadFont that accepts
an area_id and loads the font from memory. A size and offset may
optionally be provided to allow for an area that contains more
than just a font.

BFont: Implement BFont::BoundingBox

Extracted as separate patch from CR 4790; implement BFont::BoundingBox
as it was in BeOS. Returns a BRect that encloses any character in a
font, scaled by the font size.

Since the FreeType bbox is only valid for vector outlines, for bitmap
fonts, return a BRect with the dimensions of the bitmap font that is
closest to the font size.

Tested with CharacterMap. Will update CharacterMap to use the bounding
box once this change is landed.

Note that bitmap font rendering doesn't appear to work at all.

kernel/OS.h: Include sys/types.h instead of pthread.h.

This avoids polluting the namespace significantly. Also adjust
all files which depended on this behavior to include pthread.h
directly.

Implementation of BFont::Blocks

BFont::Blocks is now implemented in ServerFont, via a call through the
app_server. It uses fontconfig to iterate through a charset of a font
and stores the defined blocks in a bitmap.

A new API was added, BFont::IncludesBlock, that will allow for arbitrary
testing of a given Unicode block. Since nothing is cached, searching
through an entire charset for a series of Unicode blocks can be quite
slow. In a given block there may be only 1 or 2 characters actually
defined so every character within a block needs to be checked until one
is found, which in a degenerate case will mean the entire block is
checked.

BStringView: added truncation support.

* Added new truncation mode B_NO_TRUNCATION.
* The Truncation()/SetTruncation() methods itself are Dano-compatible,
however, there was no B_NO_TRUNCATION.

Font: Work on support for spacing modes.

* Change default spacing to B_BITMAP_SPACING. The BeBook does not document
what the default spacing is, and I have no BeOS install handy to check.
However, I believe that B_BITMAP_SPACING is what should be the default,
since it gives the best visible result for the common use-case.
In terms of implementation, there is no change, since spacing was ignored
until now and the behavior was that of B_BITMAP_SPACING. This change could
however break BeOS apps which assume B_CHAR_SPACING is the default and don't
set it on new when they need it. Sample code in the BeBook however shows
setting B_CHAR_SPACING on a newly created BFont.
* Implement B_STRING_SPACING to do something sensible. The BeBook documentation
is completely vague in what it is actually supposed to do. Given the
possibilities of FreeType, I am implementing it to enable the use of
kerning. Kerning optimizes the spacing between two glyphs, for example, it
would decrease the spacing between "T" and "e" in the string "Test" for
our default font. Untested.

Font.cpp: Style cleanup

* Unify asterisk style
* switch indentation style of FontList declaration
* Order FontList methods according to declaration
* Use named constants in default BFont constructor for spacing and encoding.

Woops, I meant == not =

Style fixes only

Rename SetFamilyAndStyle variable to code matching the header and BeBook.

Put comments in methods, only description line outside

Style updates and remove docs from cpp file

* Replace the truncate_string() helper function with a new, simplified version.
* Remove no longer necessary support functions.
* The new version uses a single BString as input/output parameter and only
modifies that one by removing non-fitting chars and inserting the ellipsis
where appropriate, so avoids copying around bytes/chars/strings in a few
places. It uses the new Chars functions of BString so also no need for manual
multibyte handling.
* Adjusted the BFont and ServerFont usage of truncate_string() which are both
simplified by using the single BString. It avoids a lot of temprary
allocations and string copying. The char * version of BFont
GetTruncatedStrings() now uses the BString version and not the other way
around anymore which requires us to allocate temporary BString objects, it's
not worse than before though.
* This fixes a bunch of problems with the previous functions like always
prepending the ellipsis for B_TRUNCATE_BEGINNING, crashing on short enough
widths, violating the width in the B_TRUNCATE_END case when the width was
short enough, non-optimal truncation in a few cases and sometimes truncation
where none would've been needed. Also fixes #4128 which was a symptom of the
broken B_TRUNCATE_BEGINNING.

Patch by Andrej Spielmann (GSoC):
* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.

All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

* complete overhaul of the font/glyph caching
* the previous AGG implementation is superfluous
* the new implementation is based on that one, but in a way that allows
read/write locking to the list of cache entries (fonts) as well as
read/write locking to the cached glyphs per individual font cache entry
* new GlyphLayoutEngine.h, which is to be the central place for layouting
glyphs along the baseline.
It handles the locking for getting the font cache entries.
It works by giving it a template class GlyphConsumer which does the
actual work.
* changed AGGTextRenderer to use the new font cache
* changed ServerFont::StringWidth(), and the bounding box stuff to use it
* changed DrawingEngine, it doesn't need the global font lock anymore
* our BFont thought that GetBoundingBoxesAsGlyphs and GetBoundingBoxesAsString
is the same, which of course it isn't, hence the two separate functions...
AsGlyphs just gets the bounding box of each glyph in a string, not treating
the string as an actual word
AsString adds the offset of the glyph in the word to the bounding box
* changed ServerProtocol.h accordingly for the different bounding box meaning

* implemented "false bold" for text rendering. It is a new property
of BFont. You can BFont::SetFalseBoldWidth(float) a width on a
BFont object, and it will cause the glyph shapes to be run through
an AGG "contour converter" so that they become thicker or thinner.
IIRC, this is commonly referred to as "false bold". The "width" value
is the distance in pixels that the new glyph outline will be offset
from the original outline.

It would be nice if someone could look at my change to View.h with
regards to the B_FONT_ALL flag.

Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

* BFont::Face() was almost always wrong - also on the server side,
_TranslateStyleToFace() was broken.
* a clean font was not correctly initialized to be_plain_font
* BFont::GetFamilyAndStyle() did not work correctly if either family
or style was NULL - which is allowed, and shouldn't have let it abort
its task.
* FontServer::GetStyle() by ID did not work reliably under certain
circumstances (but those were not reached with the current server)
* BFont::SetFamilyAndStyle() did not work when family was NULL, and
it also never set fFace correctly.
* Introduced a FontFamily::GetStyleWithFace()
* Renamed some FontFamily/FontStyle methods from ie. GetID() to ID()
to match the style used everywhere else in BeOS.
* Removed AS_SET_FAMILY_NAME as its no longer in use.
* Lots of cleanup and simplification.

Added a note in GetEscapements

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12688 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented BFont::GetEscapments() float version. It is pretty rough yet, but appears to handle UTF8 correctly. The optional escapement_delta is currently ignored. I didn't touch other functionality too much, until I know more about it.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12645 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12589 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added support for GetEscapements() too. Still unfinished. Maybe this should be moved elsewhere?

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12216 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented BPortLink::AttachShape and BPortLink::ReadShape and used them for passing the shapes in AS_GET_GLYPH_SHAPES.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12215 a95241bf-73f2-0310-859d-f6bbb57e9c96

*Doh* Forgot a couple minor edits before initial checkin


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1497 a95241bf-73f2-0310-859d-f6bbb57e9c96

Initial framework checkin. Rudimentary functions implemented.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1495 a95241bf-73f2-0310-859d-f6bbb57e9c96

BStringView: added truncation support.

* Added new truncation mode B_NO_TRUNCATION.
* The Truncation()/SetTruncation() methods itself are Dano-compatible,
however, there was no B_NO_TRUNCATION.

Font: Work on support for spacing modes.

* Change default spacing to B_BITMAP_SPACING. The BeBook does not document
what the default spacing is, and I have no BeOS install handy to check.
However, I believe that B_BITMAP_SPACING is what should be the default,
since it gives the best visible result for the common use-case.
In terms of implementation, there is no change, since spacing was ignored
until now and the behavior was that of B_BITMAP_SPACING. This change could
however break BeOS apps which assume B_CHAR_SPACING is the default and don't
set it on new when they need it. Sample code in the BeBook however shows
setting B_CHAR_SPACING on a newly created BFont.
* Implement B_STRING_SPACING to do something sensible. The BeBook documentation
is completely vague in what it is actually supposed to do. Given the
possibilities of FreeType, I am implementing it to enable the use of
kerning. Kerning optimizes the spacing between two glyphs, for example, it
would decrease the spacing between "T" and "e" in the string "Test" for
our default font. Untested.

Font.cpp: Style cleanup

* Unify asterisk style
* switch indentation style of FontList declaration
* Order FontList methods according to declaration
* Use named constants in default BFont constructor for spacing and encoding.

Woops, I meant == not =

Style fixes only

Rename SetFamilyAndStyle variable to code matching the header and BeBook.

Put comments in methods, only description line outside

Style updates and remove docs from cpp file

* Replace the truncate_string() helper function with a new, simplified version.
* Remove no longer necessary support functions.
* The new version uses a single BString as input/output parameter and only
modifies that one by removing non-fitting chars and inserting the ellipsis
where appropriate, so avoids copying around bytes/chars/strings in a few
places. It uses the new Chars functions of BString so also no need for manual
multibyte handling.
* Adjusted the BFont and ServerFont usage of truncate_string() which are both
simplified by using the single BString. It avoids a lot of temprary
allocations and string copying. The char * version of BFont
GetTruncatedStrings() now uses the BString version and not the other way
around anymore which requires us to allocate temporary BString objects, it's
not worse than before though.
* This fixes a bunch of problems with the previous functions like always
prepending the ellipsis for B_TRUNCATE_BEGINNING, crashing on short enough
widths, violating the width in the B_TRUNCATE_END case when the width was
short enough, non-optimal truncation in a few cases and sometimes truncation
where none would've been needed. Also fixes #4128 which was a symptom of the
broken B_TRUNCATE_BEGINNING.

Turned FontList into a singleton.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34374 a95241bf-73f2-0310-859d-f6bbb57e9c96

* At least pretend to support all unicode blocks, and don't make such
obvious lies.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29867 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Andrej Spielmann (GSoC):
* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.

All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

Patch by Andrej Spielmann (GSOC):
* Add a private BFont API that sets/gets the subpixel and hinting configuration
of the app_server. Currently, the options are boolean, but may be changed
to modes later.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26363 a95241bf-73f2-0310-859d-f6bbb57e9c96

Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24159 a95241bf-73f2-0310-859d-f6bbb57e9c96

* fExtraFlags was not maintained in various places, most importantly nowhere
in SetFamilyAndStyle(), this should fix stuff like IsFixed() not working


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22189 a95241bf-73f2-0310-859d-f6bbb57e9c96

* complete overhaul of the font/glyph caching
* the previous AGG implementation is superfluous
* the new implementation is based on that one, but in a way that allows
read/write locking to the list of cache entries (fonts) as well as
read/write locking to the cached glyphs per individual font cache entry
* new GlyphLayoutEngine.h, which is to be the central place for layouting
glyphs along the baseline.
It handles the locking for getting the font cache entries.
It works by giving it a template class GlyphConsumer which does the
actual work.
* changed AGGTextRenderer to use the new font cache
* changed ServerFont::StringWidth(), and the bounding box stuff to use it
* changed DrawingEngine, it doesn't need the global font lock anymore
* our BFont thought that GetBoundingBoxesAsGlyphs and GetBoundingBoxesAsString
is the same, which of course it isn't, hence the two separate functions...
AsGlyphs just gets the bounding box of each glyph in a string, not treating
the string as an actual word
AsString adds the offset of the glyph in the word to the bounding box
* changed ServerProtocol.h accordingly for the different bounding box meaning


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21797 a95241bf-73f2-0310-859d-f6bbb57e9c96

attach missing args for AS_GET_EDGES


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20516 a95241bf-73f2-0310-859d-f6bbb57e9c96

* implemented "false bold" for text rendering. It is a new property
of BFont. You can BFont::SetFalseBoldWidth(float) a width on a
BFont object, and it will cause the glyph shapes to be run through
an AGG "contour converter" so that they become thicker or thinner.
IIRC, this is commonly referred to as "false bold". The "width" value
is the distance in pixels that the new glyph outline will be offset
from the original outline.

It would be nice if someone could look at my change to View.h with
regards to the B_FONT_ALL flag.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19547 a95241bf-73f2-0310-859d-f6bbb57e9c96

GetEscapements() didnt' take the font spacing into account. Looks like the spacing is ignored by the font backend, though, am I correct?

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18990 a95241bf-73f2-0310-859d-f6bbb57e9c96

Enabled *_font_cache_info functions - used by Scripture Guide 0.8.0


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17436 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed moreUTF8.h to utf8_functions.h.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17239 a95241bf-73f2-0310-859d-f6bbb57e9c96

Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16559 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added LinkReceiver methods that return the length of the string.
* AS_GET_STRING_WIDTHS now uses this method to send the strings to the app_server;
ie. it no longer sends the whole strings, and it saves sending the string length
separately.
* BFont::StringWidth() will now always return 0.0f in case of an error (instead of
some random value)
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16525 a95241bf-73f2-0310-859d-f6bbb57e9c96

More work on the BFont special functions.

* Reworked functions like GetEscapements(), GetBoundingBoxesAsString() and GetGlyphShapes() completely
* Made the ServerFont functions uniform in their prototypes and cleaned out unnecessary arguments
* Added new UTF8 handling functions to moreUTF8.h that are now used by ServerFont
* Put the common transformations of the FT_Face into an own GetTransformedFace() to lessen code duplication

In other words, ServerFont is now cleaned and handles UTF8 pretty efficiently. Some ToDo's are still left though.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16241 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed GetGlyphShapes(). The BShapes that are outputted are correct now but the app_server still cannot draw them correctly.
* Changed the allocation to new for GetGlyphShapes() and GetEscapements() as the data is deleted in ServerApp.cpp
* Minor cleanup

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16231 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

Now also sorts the font list - unlike the app_server, it could also take the
user's locale into account.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14827 a95241bf-73f2-0310-859d-f6bbb57e9c96

Oops: 1) fixed warning, 2) added missing bracket (in PrintToStream() output).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14808 a95241bf-73f2-0310-859d-f6bbb57e9c96

Made BFont::PrintToStream() a bit more useful.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14807 a95241bf-73f2-0310-859d-f6bbb57e9c96

New private function _get_system_default_font_() that makes the AS_GET_DEFAULT_SYSTEM_FONT
command available to the fonts preferences.
Now uses the maximum length argument for LinkSender::AttachString() it got from the API user.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14801 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The font list is now cached client-side. The app_server is only queried for
updates.
* Optimized retrieving the font list from the server.
* This greatly simplifies the app_server communication for getting the font
list as well - there are now only 2 commands instead of 6.
* Moved extra font flags creation from ServerApp to FontStyle::Flags().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14751 a95241bf-73f2-0310-859d-f6bbb57e9c96

BFont::_GetExtraFlags() no longer returns a status value, but fills in default
values in case the server communication failed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14742 a95241bf-73f2-0310-859d-f6bbb57e9c96

More font work:
* Simplified server communication a bit: instead of separate queries for font
direction, "is fixed", ... there is now a private extra flags field that is
filled on demand.
* The server command names now describe what the command does, and are not simply
named after the BFont method (AS_SET_FAMILY_AND_STYLE vs. AS_GET_FAMILY_AND_STYLE_IDS).
* Replaced B_SET_SYSFONT_{PLAIN|BOLD|FIXED} with a single B_GET_SYSTEM_FONTS.
* Rewrote Font.h and added our license.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14741 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed some communication mismatches I introduced earlier: we are no longer sending
whole font_family/style strings (each 64 bytes), but only strings, because they
are usually shorter than 64 bytes.
This should fix the StyleEdit problems Stefano were seeing.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14628 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added and implemented AS_GET_FONT_FILE_FORMAT - currently, it returns always
B_TRUETYPE_WINDOWS, though.
* possibly returned an uninitialized error code in some BFont methods.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14622 a95241bf-73f2-0310-859d-f6bbb57e9c96

More font work:
* simplified BFont::SetFamily*() server communication - there is now only
AS_SET_FAMILY_AND_STYLE left, but at least that one works correctly.
* BFont::fFace is now always updated correctly.
* Moved the fFace masking to the server - BFont doesn't know enough to do
this correctly, anyway.
* Only one version of get_font_style() worked correctly.
* Font family/style ID and index were used completely mixed up - this
would have become an issue as soon as the font list changes during
runtime.
* Enabled AS_GET_FONT_DIRECTION again - missing functionality should only
be taken into account on lowest level as long as it can be emulated.
* Made FontServer a bit clearer to use (more to come).
* fixed several allocation leaks in the font server communication.
* New FontStyle::Direction() method, that currently only returns
B_FONT_LEFT_TO_RIGHT, though.
* more cleanup.

Followed Marcus' suggestion and made fHeight mutable - not nice, but cleaner
than casting away the const.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14614 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented caching of the font_height, as suggested by Stefano - seems to work fine.
Also added some TODO items (mostly to SetFace()).

Looks like Axel did already all the changes I wanted to do.... so I'll just add a comment

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14609 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed a bunch of bugs in the font sub-system:
* BFont::Face() was almost always wrong - also on the server side,
_TranslateStyleToFace() was broken.
* a clean font was not correctly initialized to be_plain_font
* BFont::GetFamilyAndStyle() did not work correctly if either family
or style was NULL - which is allowed, and shouldn't have let it abort
its task.
* FontServer::GetStyle() by ID did not work reliably under certain
circumstances (but those were not reached with the current server)
* BFont::SetFamilyAndStyle() did not work when family was NULL, and
it also never set fFace correctly.
* Introduced a FontFamily::GetStyleWithFace()
* Renamed some FontFamily/FontStyle methods from ie. GetID() to ID()
to match the style used everywhere else in BeOS.
* Removed AS_SET_FAMILY_NAME as its no longer in use.
* Lots of cleanup and simplification.

Some cleanup, some removed typos, some unification, some fixes and some added todos. Most of it related to client-server communication. Apps that rely on BFont stuff should work now (StyledEdit, Fonts, Keymap, Menu, ...). Or should not hang/quit at startup at least.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13625 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented B_TRUNCATE_MIDDLE, since truncate_strings() could corrupt memory
before in this mode. Some further cleanup, only B_TRUNCATE_BEGINNING is still
left.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13154 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed BAppServerLink to AppServerLink, BPortLink to PortLink, LinkMsgReader
to LinkReceiver, LinkMsgSender to LinkSender, and put everything into the
BPrivate namespace.
Made AppServerLink a cheap object - it will use the applications receiver/sender
and not create its own buffers.
Fixed broken communication stuff here and there (mostly Font.cpp).
Put the newly introduced set|get_system_colors() into the BPrivate namespace -
please don't introduce private functions into the public namespace!!!
Also fixed their broken communication use, as Darkwyrm obviously forgot about
it again: the sequence Flush(); GetNextMessage() without error checking is
purely wrong and can make the app hang and/or crash! :-)
Other minor cleanup.
The input_server used some test mode with the haiku build target which is
probably wrong.
Hopefully I did not forget anything this time.

More fixes to the prefs panel. In fact, for all practical purposes, it should be done.
Added private function _set_system_font_() to not use R5's hack


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13031 a95241bf-73f2-0310-859d-f6bbb57e9c96

huge cleanup, support for SetSizeLimits, support for truncating strings, numerous decorator bug fixes, Layer does not draw when view color is B_TRANSPARENT_COLOR, cleaner dispatching of mouse events to the WinBorder in RootLayer, commented the char map selection in the font server, as it seems glyph lookup by unicode index works much better with the default map

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12945 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added a note in GetEscapements

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12688 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented BFont::GetEscapments() float version. It is pretty rough yet, but appears to handle UTF8 correctly. The optional escapement_delta is currently ignored. I didn't touch other functionality too much, until I know more about it.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12645 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added support for GetEscapements() too. Still unfinished. Maybe this should be moved elsewhere?

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12216 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented BPortLink::AttachShape and BPortLink::ReadShape and used them for passing the shapes in AS_GET_GLYPH_SHAPES.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12215 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added support for BFont::GetGlyphShapes. Not finished yet and untested, delivery method as to be changed.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12214 a95241bf-73f2-0310-859d-f6bbb57e9c96

Corrected reply handling of FlushWithReply in many places what should fix some strange bugs.
