My tests were done in Win32, some time ago i had to display frames
from a Camera wich i first had to process, drawing on a graphic
control was slow, on a form was little faster, but the best
performance i achieved was using a Panel in wich i trapped all
possible paint messages or even faster making my own control and
adding a canvas like other window based controls, all the processing
and drawing was done off-screen on a buffer bitmap, i haven't
performed any speed tests with non accelerated Video Cards & OpenGL so
GL may be faster only in newer cards, dunno if using dedicated
software GL libs like SGI's and Mesa helps.
Hope it helps.
