e6069e9cf6 Arghl. Again a stupid bug caused by float having poor precision. 
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.

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.

c2ff6a4d7a Make sure to unbind the texture in tfp_mode when the underlying pixmap 
is discarded.  Windows that have previously been mapped and unmapped now
update properly when mapped again.

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.

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.
