'''OpenGL extension NV.vertex_program1_1
Overview (from the spec)
This extension adds four new vertex program instructions (DPH,
RCC, SUB, and ABS).
This extension also supports a position-invariant vertex program
option. A vertex program is position-invariant when it generates
the _exact_ same homogenuous position and window space position
for a vertex as conventional OpenGL transformation (ignoring vertex
blending and weighting).
By default, vertex programs are _not_ guaranteed to be
position-invariant because there is no guarantee made that the way
a vertex program might compute its homogenous position is exactly
identical to the way conventional OpenGL transformation computes
its homogenous positions. In a position-invariant vertex program,
the homogeneous position (HPOS) is not output by the program.
Instead, the OpenGL implementation is expected to compute the HPOS
for position-invariant vertex programs in a manner exactly identical
to how the homogenous position and window position are computed
for a vertex by conventional OpenGL transformation. In this way
position-invariant vertex programs guarantee correct multi-pass
rendering semantics in cases where multiple passes are rendered and
the second and subsequent passes use a GL_EQUAL depth test.
The official definition of this extension is available here:
