[SDL] OSX and pBuffers?

[James Tittle II]

hiya,

...I've been trying to port some demos to SDL that use pbuffers...I 
know, SDL12 doesn't include  a pbuffer api, but I figured I could work 
around that, but unfortunately I haven't been able to on OSX...

...my first attempt was to use the cgl pbuffer api's (because cgl 
underlies all the other opengl api's on OSX), but these seem to be 
broken (several bugs filed to apple)...now I'm looking at the quartz 
video driver files in SDL, and realized that the underlying opengl 
context is a NSOpenGLContext* (in SDL_PrivateVideoData)...

...so, does anyone have any ideas how to access this context, and if 
possible, use it with the other apple pbuffer api's?  For instance, it 
seems that apple wants people to "share" contexts, so would I have to 
use the NSOpenGL api for pbuffers?  If so, can I do this thru plain old 
c/c++, without using objc?  Also, is it possible to use NSOpenGLContext 
with cgl or agl pbuffer calls?

thanx,
jamie
