At this phase of development my intention is to disable any OpenGL etc.
extension of Qt to force it to use software rendering/blitting. Why do I
have to patch Mesa (which is a kind of OpenGL implementation if I'm not
wrong) if my Qt doesn't use OpenGL/EGL at all?

In a very simplyfied approach, what I only have to do in 'linuxfb'
platform plugin is copying the buffer data not to /dev/fb*, but into my
buffer... is it correct?
