[PATCH 2/9] glx: Implement GLX SetClientInfo2ARB protocol
Ian Romanick
idr at freedesktop.org
Wed Jul 4 15:21:02 PDT 2012
From: Ian Romanick <ian.d.romanick at intel.com>
The protocol is almost identical to SetClientInfoARB. The only
difference is the GL versions include an extra 4 bytes for the supported
profile.
