This is the XRender-based compositing code. The primary compositing
|
|
backend is the OpenGL-based one, which should be more powerful
|
|
and also possibly better documented. This backend is mostly for cases
|
|
when the OpenGL backend cannot be used for some reason (insufficient
|
|
performance, no usable OpenGL support at all, etc.)
|
|
The plan is to keep it around as long as needed/possible, but if it
|
|
proves to be too much hassle it will be dropped in the future.
