OpenGL extension ARB.geometry_shader4
 
This module customises the behaviour of the 
OpenGL.raw.GL.ARB.geometry_shader4 to provide a more 
Python-friendly API
 
Overview (from the spec)
        
        ARB_geometry_shader4 defines a new shader type available to be run on the
        GPU, called a geometry shader. Geometry shaders are run after vertices are
        transformed, but prior to color clamping, flat shading and clipping.
        
        A geometry shader begins with a single primitive (point, line,
        triangle). It can read the attributes of any of the vertices in the
        primitive and use them to generate new primitives. A geometry shader has a
        fixed output primitive type (point, line strip, or triangle strip) and
        emits vertices to define a new primitive. A geometry shader can emit
        multiple disconnected primitives. The primitives emitted by the geometry
        shader are clipped and then processed like an equivalent OpenGL primitive
        specified by the application.
        
        Furthermore, ARB_geometry_shader4 provides four additional primitive
        types: lines with adjacency, line strips with adjacency, separate
        triangles with adjacency, and triangle strips with adjacency.  Some of the
        vertices specified in these new primitive types are not part of the
        ordinary primitives, instead they represent neighboring vertices that are
        adjacent to the two line segment end points (lines/strips) or the three
        triangle edges (triangles/tstrips). These vertices can be accessed by
        geometry shaders and used to match up the vertices emitted by the geometry
        shader with those of neighboring primitives.
        
        Since geometry shaders expect a specific input primitive type, an error
        will occur if the application presents primitives of a different type.
        For example, if a geometry shader expects points, an error will occur at
        Begin() time, if a primitive mode of TRIANGLES is specified.
