Summary: example 04.pix/26.framebuffer_readback crash

Initial Comment:
the example 04.pix/26.framebuffer_readback crash pd with a segfault when creating the openGL windows
this is with curent svn (rev  3971), ubuntu 10.04

I can see 2 different problem : 
- pix_snap does not create an image (pix_info after pix_snap gives only -1)
- pix_buffer_read crash when reading this image

Message:
hmm, checked on an debian/sid machine with 2.6.38-2-amd64 and
nvidia-270.41.19 (and a fresh checkout of Gem) and still cannot reproduce.
i noticed that [pix_kaleidoscope] does not work _correctly_ on amd64
though, but if i turn that off, everything works as expected.

pix_snap does not work for framebuffer, but pix_write is working...
