20fdcf06f4 Fix blending issue with invert effect 
Actually it's more a hack and should be addressed in the next
release cycle by allowing effects to modify the scene's blend
equation.
BUG: 274424
FIXED-IN: 4.7.0

af92a4efd4 kwin: Rename sample to sampler in all shaders 
A sample is not the same thing as a sampler.

73be6657ea kwin: Replace brightness and opacity with a modulation constant 
This makes it possible to adjust both brightness and opacity
at the same time with one multiplication in the fragment shader.

28cf355b26 kwin: Fix a bug in the fragment shaders 
The alpha channel must be set to 1 before the sample is modulated
with the brightness and opacity constants, not after.

5e97ccf7e0 kwin: Normalize the texcoords in the vertex shader 2011-02-10 20:15:23 +01:00

b7ee35bba1 Invert effect ported to GLES. 
It uses a generic vertex shader and because of that it needs to
mark all windows which are inverted as transformed.
There is currently a conflict with Lanczos (or thumbnails) and with
the desktop in cube effect.

846496d2c1 Cleaned up the effects/ directory by moving each individual effect into 
its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
