Note that on X.org servers before 6.9 (and probably others as well) the length
field in the reply is computed incorrectly for GetFBConfigs and
VendorPrivateWithReply vendor_code 0x10004 (GetFBConfigsSGIX). For these
requests the reply structure begins:
	<pad bytes="1" />
	<field type="CARD32" name="numVisuals" />
	<field type="CARD32" name="numProps" />
The correct value for the length field is
	numVisuals * numProps * 2
but on broken servers the "* 2" was missing. A workaround that is correct for
all implementations is to rewrite the length field on receipt on the client
side, using the expression above.

The patch that fixed this server bug in X.org CVS is here:
	http://cvs.freedesktop.org/xorg/xserver/xorg/GL/glx/glxcmds.c?r1=1.6&r2=1.7
