Get app_server working on x86_64. With this commit, app_server now compiles and runs at boot! Nothing particularly interesting happens, just the blue background and a mouse pointer. Remote backends are broken and not compiled in, see #8834. Note that it won't be possible to build this quite yet, need to get the FreeType package uploaded.

Create uncached glyphs on demand instead of checking glyph availability upfront. This safes a HasGlyphs() call which would convert the whole string to glyph codes and look each of the glyphs up in the cache entry, just to do the same again during the loop where they are actually used. Instead we now simply switch to the write lock and look up the fallback entry when hitting the first uncached glyph. This benefits the normal case of having all glyphs cached without any drawbacks. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40186 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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26755 a95241bf-73f2-0310-859d-f6bbb57e9c96

* after my last changes to font rendering, it was about 15% slower than before (although there should be much less lock contention) * with this change, there is quite a bit of cleanup, text drawing is now about 20% faster than before the original changes to font caching, mostly due to turning off the kerning feature, which at the moment gives absolutely no benefit. The correct way of doing it might be to use kerning depending on the provided glyph spacing mode * removed fPenLocation from Painter, the usage should be more correct now, since it is now consistently applied before the coordinate transformation from view to screen (also for DrawShape() now, before any view scaling and origin offset) * Painter no longer has it's own instance of a ServerFont, instead it uses its AGGTextRenderer instance, which was per Painter again after the last change, and not global anymore, made _UpdateFont() useless * When using GlyphLayoutEngine, it supports a second pass with the same FontCacheEntry through the introduction of a FontCacheReference. This speeds up DrawString a little, since it needs to calculate the bounding box for the string, and then draw the string in a second pass. This is now done with only one FontCacheEntry lookup * I also tried to optimize the on-the-fly conversion of UTF8->CharCode away, since it was done four times per DrawString, but surprisingly, it proofed to be a slight slowdown. * introduced a shortcut in DrawingEngine::DrawString() which avoids calculating the bounding box, we are now a tiny bit faster to figure out that we don't need to draw any string than Dano In the test environment (drawing to offscreen bitmap and blitting to screen eventually), text rendering is now about 3.7 times _faster_ than Dano text rendering (directly to screen), for untransformed text. Unfortunately I cannot test on the same machine in accelerant using version of the test environment. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21822 a95241bf-73f2-0310-859d-f6bbb57e9c96
