6fd9d4e4b3 Create a new window for each tested pixmap with selfcheck, otherwise 
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).

fd2e9b54cb Funny how awesome ideas are often so awfully simple. Test whether compositing 
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.

cb4ed769aa Change from orthographic projection to a perspective projection. This allows to change z-values and rotations. 
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.

- #ifdef KWIN_HAVE_OPENGL_COMPOSITING to check for OpenGL-based compositing
- #ifdef KWIN_HAVE_XRENDER_COMPOSITING the same for XRender

ac42ba0b4f A simple solution for alpha channel hacks - ignore them :). 
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.

5faa397849 Vertex redesign - redo the way windows are split into smaller parts 
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.

9c31c4555c I apparently misunderstood the semantics of texture_from_pixmap a bit - rebind 
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.

630f5793dc Update SHM mode. 
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.

aa6d8eabc5 Add GLTexture class. This is a convenient wrapper around managing an OpenGL texture, as well as loading an image into it. Includes support for loading from QImage, QPixmap, and a file. Defaults to a GL_TEXTURE_2D target, and will scale image if necessary. 
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.

e61ecff9b9 Check that getting compositing pixmap of a window succeeded. 
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.

f060c3bfbb Improved filtering algorithm. Now fast filtering is used by default, while (depending on SmoothScale in kwinrc) bilinear filtering is used on transformed windows and screens. 
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.

392acfb28c A really nice trick from Compiz. OpenGL coordinates have Y upside 
down ( [0,0] is bottomleft, unlike topleft with X ), so simply
flip the whole scene upside down and move it up -> the coordinates
match, except for when mapping pixmap to textures.
