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

This also allows removing the confusing initPaint()/postPaint() calls in Scene.

and glTexImage texture creation. Stolen from Beryl (stolen from Looking Glass).
Not faster than TFP but faster then the original fallback glCopyTexImage
mode from glcompmgr.

Also dump drawing directly into the root window, OpenGL normally
clips the root window, so nothing is drawn. NVidia has "DisableGLXRootClipping",
but there's no way to detect that and there's still the non-db mode.

Add support for changing window brightness.
Add DialogParent effect that makes windows that are unaccessible because
of modal dialogs darker.

the right header for GLX extensions is GL/glxext.h . If it still doesn't
compile somewhere, it probably needs conditional compilation.

match, except for when mapping pixmap to textures.
