'''OpenGL extension ARB.fragment_program_shadow
Overview (from the spec)
This extension extends ARB_fragment_program to remove
the interaction with ARB_shadow.
This extension defines the program option
"ARB_fragment_program_shadow".
If a fragment program specifies the option "ARB_fragment_program_shadow"
SHADOW1D, SHADOW2D, SHADOWRECT
are added as texture targets. When shadow map comparisons are
desired, specify the SHADOW1D, SHADOW2D, or SHADOWRECT texture
targets in texture instructions.
Programs must assure that the comparison mode for each depth
texture (TEXTURE_COMPARE_MODE) and/or the internal texture
format (DEPTH_COMPONENT) and the targets of the texture lookup
instructions match. Otherwise, if the comparison mode
and/or the internal texture format are inconsistent with the
texture target, the results of the texture lookup are undefined.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/ARB/fragment_program_shadow.txt
