| '''OpenGL extension QCOM.alpha_test | |
| This module customises the behaviour of the | |
| OpenGL.raw.GLES2.QCOM.alpha_test to provide a more | |
| Python-friendly API | |
| Overview (from the spec) | |
| This extension reintroduces the alpha test per-fragment operation | |
| from OpenGL ES 1.x. Some hardware has a dedicated unit capable of | |
| performing this operation, and it can save ALU operations in the fragment | |
| shader by avoiding the conditional discard. | |
| The official definition of this extension is available here: | |
| http://www.opengl.org/registry/specs/QCOM/alpha_test.txt | |
