but whatever) default to ARGB visual if available, it's better to turn off
compositing if no GLX visual is found for depth 32.

Reverting r700026 and changing floats to doubles again. I'd probably like
to change even the ones interfacing with OpenGL which I've left for now.

The 'ignore ARGB visuals' option from Kompmgr probably doesn't make
much sense, those (usually old) apps can be run with XLIB_SKIP_ARGB_VISUALS=1 set.
Also remove the alpha clear hack used for decorations - I think decorations
instead should be fixed not to "unintentionally" have alpha set.

exposed a bug in our (ab)use of QX11Info::appDepth(). Make sure that
our buffers match the depth of the root window.
Thanks to Fredrik for the hint about DefaultDepth().

for use in effects (and not only). Now a list of window quads (=window areas)
is created at the beginning of the paint pass, prepaint calls can modify
the split itself (i.e. divide it into more parts). The actual paint calls
can then modify these quads (i.e. transform their geometry). This will allow
better control of how the split is done and also allow painting e.g. only
the decoration differently. Still work in progress, but it works.
Also pass data to prepaint functions in a struct, as there is
already quite a number of them.

update properly when mapped again.

only when the compositing pixmap changes (as in: a new one), not when its contents
change. This finally makes TFP faster than SHM (70% vs 45% of non-composited
performance) and should about match Compiz/Beryl. After this change also strict
binding may finally make sense.

array when rendering.
- Rearrange some renderGLGeometry() parameters.
- Don't use opengl arrays and glDrawArrays() when rendering a small number of vertices since in this
case overhead of enabling/disabling the array is too big. Use immediate mode instead in such case.

For 16bpp pixmaps, we use GL_RGB and GL_UNSIGNED_SHORT_5_6_5 with
glTex(Sub)Image2D, which means that SHM mode works with 16bpp X
servers.
Also, only create one XShmPixmap per damaged pixmap, instead of one
per (optimised) damage rectangle. Now we can use GL_RGB textures for
24bpp pixmaps, just like fallback mode does and tfp mode can.

The render target is used to render the scene (or part of it) onto texture. This texture can then be used
e.g. to do some postprocessing.
Demo effect coming soon.
Move checkGLError() to kwineffects.*
Add GLTexture ctor which takes width and height and creates an empty texture (to be used with
GLRenderTarget to render onto it)
svn path=/branches/work/kwin_composite/; revision=655489
There's also a kwineffects library now, containing the effects API, which makes it possible to write
third-party effects.
API isn't complete yet and for now just two effects have been converted but I'm working on it :-)

Also add SceneOpenGL::Texture class, based on GLTexture. Optimised for SceneOpenGL::Window, this adds support for loading from an X Pixmap, as well as taking advantage of texture_from_pixmap/shm when available. Automatically detects what texture target should be used, so be sure to enableUnnormalizedTexCoords() before painting.
Make SceneOpenGL::Window, BoxSwitchEffect, and ExplosionEffect use the new classes.
