Neither should be difficult. I just haven't had the time yet. I keep getting
distracted with other problems. ;-)

The principle advantage of using OpenGL for rendering on OS X is that it fits
in better with how the Quartz compositor works, so should allow better
performance in windowed mode.
Basically, E-UAE will render to a software buffer as usual, this gets uploaded
to the video card as a texture and blitted to the screen using 3D hardware.
As a side-effect you get OpenGL scaling/filtering basically for free - which
is nice.

It could use SDL or not. SDL just provides a way to get your hands an OpenGL
context.
