[Piglit] [PATCH 4/4] tests: Add API tests for KHR_texture_compression_astc_{ldr, hdr}
Nanley Chery
nanleychery at gmail.com
Wed Jul 29 09:23:39 PDT 2015
From: Nanley Chery <nanley.g.chery at intel.com>
These tests check that the GL errors returned by valid and invalid API calls
are as defined by the spec.
