'''OpenGL extension OES.point_size_array
This module customises the behaviour of the
OpenGL.raw.GLES1.OES.point_size_array to provide a more
Python-friendly API
Overview (from the spec)
This extension extends how points and point sprites are rendered
by allowing an array of point sizes instead of a fixed input point
size given by PointSize. This provides flexibility for applications
to do particle effects.
The vertex arrays will be extended to include a point size array.
The point size array can be enabled/disabled via POINT_SIZE_ARRAY_OES.
The point size array, if enabled, controls the sizes used to render
points and point sprites. If point size array is enabled, the point
size defined by PointSize is ignored. The point sizes supplied in the
point size arrays will be the sizes used to render both points and
point sprites.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/OES/point_size_array.txt
