IIRC glscene supports most (if not all) of this. It works pretty well 
for me on 32-bit linux with gtk1 even thou there are still some 
glitches regarding bitmap manipulation.
It should also work with gtk2, but I'm not using gtk2 yet, so I don't 
know about the related problems.
It also compiles and runs on 64-bit, however, there are more problems to 
expect.
Some demos work, some need a little tweaking. Patches are welcome.
Just be sure to use the svn version of glscene and report problems/send 
patches in mantis (project "Lazarus-CCR", category "glscene").
Also consider joining the #glscene channel on frenode.net irc.
