I was wondering whether it is possible to enable/disable alpha on a composition's layer.
The reason for doing this is to prevent alpha component from rendering out of the video board's key output port. My application is rendering compositions using QCRenderer and doing a pixel read back from opengl buffer. For those who have never used video boards, there are usually two video output channels (key and fill). Key contains alpha and fill contains RGB.
