| Overview |
| |
| This extension adds an accuracy hint for the color matrix. It |
| allows the program to trade off precision for speed. |

| 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. |
