remote display of GL apps between a big-endian server and a little-endian client or vice versa doesn't work in 1.20.x
Since the changes that went in for using the glxvnd layer for dispatch in commit d8ec33fe, we are unable to remote display any GL app between a LE-server/BE-client or vice versa. glxgears, for eg., errors out being unable to find a RGB, double-buffered visual.
Remote display on like-architectures is ok. Reproduced on both Solaris and OpenBSD (thanks ajacoutot)
