menu/background: backgrounds get to know the parent component

Backgrounds now know the parent control, they are painted in, to query
the size.

Backgrounds are not allowed to use glClear anymore, should only draw
something during the extend of the parent control and should take care
to do not modify the opengl cursor position.
