Intel's OpenGL Linux Driver Is Now One Step Closer To GL 4.4: ARB_query_buffer_object

With the latest code landing in Mesa Git this afternoon, the GL_ARB_query_buffer_object has been wired up for Intel's i965 OpenGL driver.

ARB_query_buffer_object up to now has just been supported by the Nouveau NVC0 driver while now Intel's driver has joined the part with meeting this requirement needed by OpenGL 4.4. The support landed via this commit and is available for Intel Haswell graphics hardware and newer.

Aside from the FP64-related work to finally bring the i965 driver into a GL4 world, with the latest Git it just needs ARB_robust_buffer_access_behavior for OpenGL 4.3 compliance and finishing up the ARB_enhanced_layouts items before seeing OpenGL 4.4 compliance. For OpenGL 4.5 there still are a number of extensions outstanding.
