I've been trying to figure out GL_EXT_framebuffer_multisample,
GL_EXT_framebuffer_blit, GL_ARB_texture_non_power_of_two, and
GL_ARB_texture_rectangle for a post processing framework that I've
been working on. I think I have it all sorted and things are working
nicely.

There's not a lot of info out there on how to use the multisample
rendering extensions. I've decided to release the code to the demo
that I wrote when I was trying to figure all this out. I've since
cleaned up the code and heavily commented it. Hopefully this will be
of benefit to anyone about to go down the same path.
