Description

OpenGL specifies that implementations should rasterize lines using the diamond exit rule (a slightly modified version of Bresenham’s algorithm). To implement OpenGL some implementations have a device-level compatibility mode to rasterize lines according to the OpenGL specification.

This extension allows OpenGL emulation layers to enable the OpenGL compatible line rasterization mode of such implementations.
