It uses a new config group Blacklist in kwinrc with two subgroups for Lanczos and Blur.
The key of each entry in the group referrences the vendor either using GL_VENDOR or GL_RENDERER, e.g. "Intel" in renderer for Intel based chips.
The value of the entries is a stringlist containing exactly the renderer information. This way it is possible to blacklist several mesa driver versions which are buggy.
The blacklist is currently empty and will be filled with a kconf update script (which could also be done by distributions). So all users who experience problems and are subscribed to the bugs receiving this message, please upload your glxinfo.
An example for a blacklist:

Used in cube animation for all sticky windows and in desktop grid for the add/remove desktops window.

The texture needs to be drawn on screen coordinates on the offscreen
framebuffer in the horizontal pass, otherwise pixels that fall below
the screen won't be clamped to the screen edge in the subsequent
vertical pass. This is because the offscreen buffer is the same size
as the screen.
This change also gets rid of the need to clear the offscreen buffer
before blurring the screen contents behind each window, and reduces
the CPU computations done on the blur region.

This makes the blending work correctly when the alpha bits are zero,
which is apparently the case with NVidia.

Applications can use this hint to specify the region under the
the window where the blur effect will be applied.

its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
