cd98bc12d5 Shared implementation of rendering gl geometry.

cc1a7a9eca Add GLRenderTarget class. 
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)

0353f3376e Make effects actual plugins, so it's possible to load them on runtime. 
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 :-)

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.
