OpenGL.GL.VERSION.GL_2_0

OpenGL extension VERSION.GL_2_0

This module customises the behaviour of the OpenGL.raw.GL.VERSION.GL_2_0 to provide a more Python-friendly API

The official definition of this extension is available here: http://www.opengl.org/registry/specs/VERSION/GL_2_0.txt

glVertexAttribPointer( index , size , type , normalized , stride , pointer )

Set an attribute pointer for a given shader (index)

index: the index of the generic vertex to bind, see glGetAttribLocation for retrieval of the value, note that index is a global variable, not per-shader
size: number of basic elements per record, 1,2,3, or 4
type: enum constant for data-type
normalized: whether to perform int to float normalization on integer-type values
stride: stride in machine units (bytes) between consecutive records, normally used to create "interleaved" arrays
pointer: data-pointer which provides the data-values, normally a vertex-buffer-object or offset into the same.

This implementation stores a copy of the data-pointer in the contextdata structure in order to prevent null- reference errors in the renderer.
