Conversion to FragmentsThe conversion of a group to fragments is controlled with

Let
(either
A fragment arising from a group consisting of color data
takes on the color index or color components of the group;
the depth and texture coordinates are taken from the current raster
position's associated data.
A fragment arising from a depth component takes the component's depth
value;
the color and texture coordinates are given by those associated
with the current raster position.
In both cases texture coordinates s, t, and r are
replaced with Groups arising from DrawPixels with a format of STENCIL_INDEX are treated specially and are described in section 4.3.1.
