'''OpenGL extension APPLE.vertex_program_evaluators
This module customises the behaviour of the
OpenGL.raw.GL.APPLE.vertex_program_evaluators to provide a more
Python-friendly API
Overview (from the spec)
This extension allows the one- and two-dimensional evaluators to be used
with vertex program attributes. The operation of this extension is
precisely analogous to the operation of the normal evaluators.
Where normal evaluators are enabled with Enable(MAP1_VERTEX_3), for
example, attribute evaluators are enabled with
EnableVertexAttribAPPLE(index, VERTEX_ATTRIB_MAP1_APPLE).
Where the size (1, 2, 3, or 4) of a normal evaluator is embedded in the
token for that evaluator (for example, MAP1_VERTEX_3 has size 3),
attribute evaluators give the size as an argument to MapVertexAttrib**APPLE.
The 1D and 2D evaluator order, domain, and coefficients are given as
arguments to MapVertexAttrib**APPLE, with exactly the same meaning and
restrictions as the same arguments to Map1f, Map2f, Map1d, & Map2d.
The evaluator order, domain, and coefficients may be queried with
GetVertexAttrib*vARB, with the same operation as GetMap*v.
The official definition of this extension is available here:
