patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions
