| '''OpenGL extension EXT.blend_logic_op |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.EXT.blend_logic_op to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| A single additional blending equation is specified using the interface |
| defined by EXT_blend_minmax. This equation is a simple logical |
| combination of the source and destination colors, where the specific |
| logical operation is as specified by LogicOp. While only the XOR |
| operation may find wide application, the generality of full logical |
| operations is allowed. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/EXT/blend_logic_op.txt |
