at the same time (in other words, only when activating compositing using the kcm).
Currently selfcheck causes bad flicker (due to X mapping the overlay window
for too long?) which looks bad during KDE startup. With this patch, KDE startup
is without any flicker.

(i.e. currently it allows to enable compositing even if self-check fails).
Not recommended of course, and it's be still nice to get self-check work
reliably.

second test fails for some reason with BadAlloc in glXCreatePixmap().
Maybe nvidia bug, but could be also some hidden KWin bug (according
to GLX docs, glXCreatePixmap() can give BadAlloc only when it can't
allocate, which is nonsense here, but glXCreateWindow() says that
BadAlloc may mean calling it twice on the same window, so maybe
here it's twice with the same pixmap - I don't see where the bug
could be though).

really works by simply trying to do it and test the result - create a small
testing window with known content, do the same with it like with normal
windows, grab the screen contents, compare with the original, doesn't match? -> fail.
It still would be nice to have something similar for performance.

Therefore zScale, zTranslate and new RotationData are added to ScreenPaintData and WindowPaintData. So it is possible to define zTranslation and rotations without using OpenGL directly. The change only affects OpenGL compositing. XRender is not changed.

Also slightly redo the #define's for effects, now it's:
- #ifdef KWIN_HAVE_COMPOSITING to check whether there's any compositing support at all
- #ifdef KWIN_HAVE_OPENGL_COMPOSITING to check for OpenGL-based compositing
- #ifdef KWIN_HAVE_XRENDER_COMPOSITING the same for XRender

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.

our buffers match the depth of the root window.

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.

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.

It may fail (or "fail") if the window is not mapped or if the geometry
doesn't match, both of which may happen due to the asynchronous
nature of X.

Optionally, if SmoothScale is set to 2, trilinear filtering will be attempted instead of bilinear. This requires GL_ARB_texture_non_power_of_two, GL_EXT_framebuffer_object, and valid mipmaps.
