           Summary: Patch to utilize OpenGL environment mapping
           Product: ioquake3
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: Video

This patch includes a re-written RB_CalcEnvironmentTexCoords() to just use pure
OpenGL calls to initiate environment mapping, instead of the current cpu-based
implementation. As a bonus, a new tcGen type, 'reflection' causes the engine to
initiate OpenGL reflection mapping, which is good for water surfaces and
anything else that needs a flat reflection.
