This is actually a bloody hack by forcing the screen to be
repainted in each frame. This needs to be fixed in a different
way or we at least have to turn blur off by default for GLES in
the next release.
Optimize the region of the screen that's painted in each frame,
and paint the windows top-to-bottom when the damaged region doesn't
intersect any blurred areas.
All previously existing windowAdded methods are renamed to slotWindowAdded.
EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is
emitted a little bit earlier than the previous direct method call. This might
change behavior.
Another signal is added to Workspace to signal that an unmanaged is added.
Since the EffectFrames have been moved into KWin core nothing in the
Effects lib actually used Plasma. The only remaining method is moved
to core as it's not used in the Effects. The Effects itself still
link against Plasma, so nothing changes for them.
The Plasma includes in the kwineffects header seemed to pull in
quite some additional headers, so the includes in some effects have
to be adjusted (most often KConfigGroup). This should speed up the
compilation of the library and the effects.
It now uses a GLShader for GLSL shaders and pushes it using the
ShaderManager.
It does not work with the nouveau driver plus GLES, but it works
with fglrx + desktop GL 2.x, so I assume it is a driver problem here.
Adding a new AbilityUsesBlurBehind which can be set by decorations with
alpha channel to request that the background can be blurred. This improves
the situation for our completely opaque default Oxygen decoration.
This change is a behavior change in comparison to 4.5! Translucent decorations do
not get blurred by default any more.

- Don't announce support to clients if the shader failed to compile,
or the FBO is invalid.

Currently only scaled or translated windows were excluded,
but it is possible to also have windows with just changed
window quads (e.g. magic lamp).

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.
