OpenGL.GL.NV.primitive_restart

OpenGL extension NV.primitive_restart
This module customises the behaviour of the OpenGL.raw.GL.NV.primitive_restart to provide a more Python-friendly API
Overview (from the spec)
This extension allows applications to easily and inexpensively restart a primitive in its middle. A "primitive restart" is simply the same as an End command, followed by another Begin command with the same mode as the original. The typical expected use of this feature is to draw a mesh with many triangle strips, though primitive restarts are legal for all primitive types, even for points (where they are not useful).
Although the EXT_multi_draw_arrays extension did reduce the overhead of such drawing techniques, they still remain more expensive than one would like.
This extension provides an extremely lightweight primitive restart, which is accomplished by allowing the application to choose a special index number that signals that a primitive restart should occur, rather than a vertex being provoked. This index can be an arbitrary 32-bit integer for maximum application convenience.
In addition, for full orthogonality, a special OpenGL command is provided to restart primitives when in immediate mode. This command is not likely to increase performance in any significant fashion, but providing it greatly simplifies the specification and implementation of display list compilation and indirect rendering.
