Intel's i965 Mesa Driver Finishes Off Another OpenGL 4.5 Extension (ARB_cull_distance)

While the Intel i965 Mesa driver is currently at OpenGL 3.3 while waiting for the FP64 support to land for hitting OpenGL 4.2, various other OpenGL 4.3/4.4/4.5 extensions continue to move along for this open-source graphics driver.

For the next Mesa release it will only be at OpenGL 4.2 (assuming the FP64 patches land in time, which isn't yet guaranteed) but many items from 4.3/4.4/4.5 have already been finished off for this graphics driver. The latest one to talk about is ARB_cull_distance support.

Kristian Høgsberg and Tobias Klausmann were working on the ARB_cull_distance support for core Mesa and the i965 driver. The Intel driver is the first within Mesa to support this extension but with the groundwork laid, hopefully the Gallium3D drivers aren't too far behind.

The OpenGL 4.5 items remaining for Intel include ARB_ES3_1_compatibility, KHR_robustness, and KHR_robust_buffer_access_behavior. But before that for OpenGL 4.3 it still has to implement ARB_robust_buffer_access_behavior and for OpenGL 4.4 it needs to finish up ARB_enhanced_layouts. This year should be quite interesting on the Mesa front.
