The OpenGL glDrawArrays function is not working when rendering from a
big-endian client application host to a little-endian display server.
No output is produced and/or the X server can crash.

Function __glXDispSwap_DrawArrays in xserver/xorg/GL/glx/render2swap.c
from the CVS head is not byte-swapping all of the values as needed.
There are two loops through the compHeader structure array, but the
extracted values are only swapped in the first loop.
