[Mesa-dev] [PATCH] i965: enable OES_primitive_bounding_box with the no-op implementation

[Ilia Mirkin]

This passes a jenkins run except for 2 tests:

dEQP-GLES31.functional.primitive_bounding_box.call_order.bbox_first_viewport_second
dEQP-GLES31.functional.primitive_bounding_box.call_order.viewport_first_bbox_second

In both cases, they assume that they can create tessellation shaders, whereas
this is not yet enabled on i965. This should fix itself when that feature is
flipped on.
