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.

Also dump drawing directly into the root window, OpenGL normally
clips the root window, so nothing is drawn. NVidia has "DisableGLXRootClipping",
