SGI_color_matrix is required.
Overview
This extension adds an accuracy hint for the color matrix. It
allows the program to trade off precision for speed.
New Procedures and Functions
None
New Tokens
Accepted by the <target> parameter of glHint and by the <pname>
parameter of GetBooleanv, GetIntegerv, GetFloatv, and GetDoublev:
COLOR_MATRIX_HINT 0x8317

Additions to Chapter 5 of the 1.1 Specification (Special Functions)
Add to section 5.6 ("Hints"):
If the <target> argument of Hint is specified as COLOR_MATRIX_HINT
then the <hint> argument indicates the desired quality of pixel
colors after transformation by the color matrix. Higher quality
may correspond to higher-precision arithmetic, although an
implementation may ignore the hint.
