Blender

This section describes per-fragment end-processing.

The following sections describe how the blender works.

Item	Description
Write Test	Describes the Write Test process.
Write to Framebuffer	Describes the mechanisms of the process up through writing fragments to the framebuffer.

The Blender performs a series of processes on the created fragment information, starting by loading information from the framebuffer and ending by writing data back to the framebuffer.

The blender decides whether to write a fragment to the framebuffer depending on the outcome of a write test. Fragments that pass the test are blended with any fragments already in the framebuffer in the same location, then writes this back to the framebuffer.
