[Piglit] [PATCH 24/25] arb_shader_image_load_store: Import image unit and uniform state tracking tests.

Francisco Jerez currojerez at riseup.net
Sun Oct 5 14:00:54 PDT 2014


Test the image unit and image uniform binding commands and then check
that the state query APIs return the expected values for all bound
image units.
