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.
