GLAMOR

GLAMOR is an acceleration library merged into the X.Org Server 1.16 that provides 2D acceleration implemented over OpenGL so X.Org DDX drivers no longer need to implement 2D-specific code-paths. GLAMOR is designed to be universal amongst OpenGL / OpenGL ES supported hardware.

t uses normal texture to represent a drawable pixmap if possible.

Why Glamor?

Basiclly, the biggest two advantages of Glamor is:

Graphic device has powerful 3D capability. To use 3D function to accelerate 2D rendering is possible and many drivers already do so.
