Enable -fvisibility=hidden on static libraries by default.

Only on non-GCC2 for now, as GCC2 does not have -fvisibility.

An opt-out is left as a possibility, and is unfortunately necessary
for libshared and libicon, as these two are used even in WebKit instead
of linking to the .a. However, libcolumnlistview, libagg, and a whole
bunch of others are now no longer exported, so this is already a major
improvement on what symbols we were leaking.

This may provide performance differences for consumers of these APIs,
as GCC and the linker are now free to merge and directly use functions
that previously could have been semantically interposed. AGG usage in
app_server, especially, may benefit.

We can also now remove the addition from libnetservices, so do that.

app_server: declare jam dependecy for AlphaMaskCache to freetype

app_server: add a cache for AlphaMasks

* If the same shape alpha mask is set again and again, we now keep
the rendered masks in a cache. On certain websites, WebKit sets
the same shape for clipping hundreds of times, which uses a lot
of time to render the masks.

* When a shape mask was generated, we put it into AlphaMaskCache.
The constructor for ShapeAlphaMask is made private and a factory
method is used for instantiation instead, which transparently
looks up in the cache whether a suitable mask was already generated
before (so the entire caching is encapsulated inside the AlphaMask
class).

* When taking a mask out of the cache, we still create a new
AlphaMask instance. However, the new instance will share the
mask bitmap with the previously generated instance (aside from
the rendering of their bitmap, AlphaMask instances are pretty
lightweight). Shape masks are only seen as identical when
their shape is the same, the inverse flag, and they have the
same parent mask.

* Cache is limited to a fixed size of currently 8 MiB, using a
simple random replacement scheme. An LRU scheme can be added in
the future if necessary. Counting of bytes for the cache size
includes parent masks of masks in the cache, even if the parent
itself is not cached. A reference counter for "indirect" cache
references keeps track of which masks are not part of the cache,
but still need to be added to the cache byte size.

* For now, only for ShapeAlphaMasks, other mask types can be added
as necessary.

app_server: Cleanup of some file locations

Update freetype package

Also use the new build feature rules

AppServer: Organize "HWInterface" classes

* Organize interface classes into directories
* Long term this will assist in the multi-head
interface / accelerant changes.
* local draws to the local hw accelerant
* remote draws to a remote connection (???)
* html5 draws to... an html5 canvas?

app_server: fixed FreeType headers dependency #8716

* added DrawingEngine.cpp

An html5 <canvas> based drawing engine

This implements an html5 rendering engine.
Inspired by the Broadway GDK backend for Gnome.
Work in progress. For now it just connects and dumps debug output.

freetype: builds against the 2.4.6 optional package.

* added optional feature package for freetype 2.4.6 gcc4/gcc2 x86 and gcc4 ppc.
* FT_CONFIG_OPTION_SUBPIXEL_RENDERING is disabled, --include-patented-code doesn't
change this setting anymore. This would require different packages.
* drop freetype sources and headers from the tree.
* fix decorators, test app server and appearance to use feature package headers.
* hybrid build untested.

Cleanup app server directory a bit by creating a font and a decorator sub folder.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42483 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Adding a remote desktop interface that operates on app_server drawing
primitives by providing a RemoteDrawingEngine and a RemoteHWInterface.
Not really optimized yet, still a bit WIP.
* Adding corresponding infrastructure like a blocking ring buffer and network
sender/receiver that are attached to the buffers to feed/drain them as well
as a RemoteMessage helper that provides a message based interface.
* Adding target screen concept to request an app to be run on a specific screen.
It's controlled by the TARGET_SCREEN environment variable which is added on
the app side and sent to the app_server.
* Right now only remote target screens are supported, in which case a new
RemoteHWInterface is created that tries to connect to the given host:port.
* Fix shape bounds when drawing, they need to be translated by the pen position
and converted to screen like the points as well. Wasn't visible though as the
bounds weren't used in the normal DrawingEngine.

bonefish + stippi:
Reworked the glyph caching:
* It is now glyph index based (a font file has an internal glyph code to
index mapping, so that for example the same fallback glyph is used for
all unsupported codes).
* We do not truncate to uint16 anymore at various places, but support
the full 32 bit char codes.
* This made it necessary to switch to an OpenHashTable based cache lookup.
* In CharacterMap, you can now see that the second Unicode plane does not
wrap around anymore.
TODO: Remove old entries from the hash table after a while to free up memory.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31780 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Introduced new header directory headers/private/system which is supposed
to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

* Started accelerant extension to be able to get the preferred mode from
the accelerant, as well as its EDID info. B_GET_PREFERRED_DISPLAY_MODE and
B_GET_EDID_INFO are both optional. The preferred mode will be taken from the
EDID info if only the latter hook is implemented, or the former returned an
error.
* Currently, the app_server should correctly set the preferred mode on start,
but no accelerant supports that yet, so it's not really tested.

will not load any graphics driver (other than VESA).

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17209 a95241bf-73f2-0310-859d-f6bbb57e9c96

* implemented view bitmap options (B_BITMAP_TILE...) in
ViewLayer (for example, fixes NetPositive rendering
HTML with a background image)
* use BRegion pool everywhere in ViewLayer
* WindowLayer update sessions distinguish between
different reasons for the update: exposed and requested -
on expose updates, the view backgrounds are cleared
immidiately (as on R5), to keep the time previous stuff
keeps showing as short as possible, while on requested
updates, the background clearing is delayed until the
client draws something, to keep the time until the client
fills a view with content as small as possible to reduce
flickering (might need more work, could be buggy yet)
* HWInterface and DrawingEngine support delayed syncing to
the graphics hardware at least for FillRect/Region. The
speed up gained by this is minor though.
* HWInterface cursor rendering uses a bit of rounding to
avoid the slight transparent shadow around the cursor
(I don't know if it is fully correct though, at least the
shasow disappeared)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17172 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed headers/private/servers/app - everything is in src/servers/app now.
* Removed DisplaySupport.h, wasn't needed anymore.
* Removed private color set functions from InterfaceDefs.cpp - we might want
something similar, but definitely not like that.
* Minor cleanup, added some missing licenses.

I get to it again in the next weeks).
