This fixes the artefacts appearing when only part of the screen is updated.
This version also brings ton of optimizations which might well increase performance
2 or 3 times on slower cards:
- Windows are not drawn twice anymore. Now they're drawn only to render target and
later changed parts of the render target are copied back onto screen.
- Shaders have been optimized. Some calculations moved from pixel shader to vertex shader.
- For ARGB windows, if window's opacity is 0 then it will stay transparent instead of being
replaced by blurred background.
- Blur effect should now play nicer with other effects, e.g. shadows.

being v2+ (right now it says just GPL, which according to GPL itself
means any GPL). Decoration clients will come later.

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.

Blur effects blurs out background of translucent windows, thus improving e.g. readability of text in
such windows.
I'll send a mail with couple of screenshots and more details to kwin list soon.
