That would be news to me. However, since the protocol number of
GLX_EXT_texture_from_pixmap changed between glproto 1.4.7 and 1.4.8 (as
it was wrong before), I highly doubt this would work with an old glproto
but a new xserver or new mesa (which changed the protocol number at the
same time, 2006-09-14). Shouldn't affect the copy path, however, I guess.
