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.

than using glRasterPos2f() - the latter causes drawing
artefacts at the bottom screen edge with some gfx cards

Effects also get access to window's vertices. This can be used to change shape of
the window, e.g. for wobble effect

class Deleted as a representation of a closed window.
