Overview

    On VPro graphics systems, rendering very short lines sometimes
    causes pixel dropouts. This hint works around the hardware issue by
    dropping back to a software line rasterization path.

New Tokens

    Accepted by the <target> parameter of glHint and by the <pname>
    parameter of GetBooleanv, GetIntegerv, GetFloatv, and GetDoublev:

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
    LINE_QUALITY_HINT_SGIX, then the <hint> argument indicates the
    desired quality of line rasterization. The NICEST hint trades off
    performance for increased pixel accuracy.
