[jitter] rtt,ctt and fbo example file crashes max 5

yes, i had checked that my card supported floats.  I've just come across
another issue with the 'jit.gl.slab.float.maxpat' patch which i guess is
related to the float issue.  i get these error messages when starting the
patch:

jit.gl.pbuffer: error binding invalid pbuffer!

jit.gl.texture: error binding readback mechanism for capture!


then max crashes when i close the patch.

in relation to the fbo issue then, is it a good idea to be using fbo
readback for each episode of jitter?  my card does support fbos. .
