New Revision: 8242

Modified:
   trunk/darkplaces/gl_backend.c
Log is attached.
eliminate two calls to qglGetDoublev that possibly slow down rendering by doing a round trip to the GPU to request the matrices. However, on the tested system, this change does absolutely nothing (233fps vs 233fps), and Xnest, forcing indirect rendering and a ssh -Y localhost did not change that. On an actual network connection however, this new way is SURE faster, as it avoids a round trip over the network.

Infinite far clip already used this method, as there is no GL helper for using the infinite far clip matrix.
