'''OpenGL extension EXT.multi_draw_indirect
This module customises the behaviour of the
OpenGL.raw.GLES2.EXT.multi_draw_indirect to provide a more
Python-friendly API
Overview (from the spec)
The ARB_draw_indirect extension (included in OpenGL 4.0 and OpenGL ES 3.1)
introduced mechanisms whereby the parameters for a draw function may be
provided in a structure contained in a buffer object rather than as
parameters to the drawing procedure. This is known as an indirect draw and
is exposed as two new functions, glDrawArraysIndirect and
glDrawElementsIndirect. Each of these functions generates a single batch
of primitives.
This extension builds on this functionality by providing procedures to
invoke multiple draws from a single procedure call. This allows large
batches of drawing commands to be assembled in server memory (via a buffer
object) which may then be dispatched through a single function call.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/multi_draw_indirect.txt
