After a little discussion on the list, I made this patch for
cocoa.m, to replace CoreGraphic by OpenGL.
Great! Thank you.
It's way faster than CG, but it requires a Mac with OpenGL capable
Graphics Card and at least 8mb of VRAM.
I think starting with G4 and Highend G3, this requirements are met.
Maybe I will try if I find some spare time, but as far as I know Apple
provides a quite powerful OpenGL emulation. Last time I ran osx on
Vesa output, everything worked just fine.
features:
[new] draws dirty lines of the window as needed, implemented with
OpenGL (used the extensions as proposed by Pierre)
[new] window can be resized
[fix] conditional builds for Leopard, without linking to a specific
sdk
[fix] lineflicker in fullscreen mode
The Question is, where to draw the line - or - if it needs a switch
for CG/OpenGL support for cocoa.
As this OpenGL implementation is based on the Apple pass-through
extensions, I don't think it'd make a good start for a generic
implementation. Additionally I believe SDL is a good choice for the
output too, as they implement optimizations for the specific
platforms. The only sad part is that I have not seen a 64-bit capable
SDL on Mac OS X ;-).
Please test and comment.

Apart from this core dump which I received after playing a bit with an
ubuntu image, the patch looks fine to me. It's a lot faster than the
previous one.
