The Raster Aspect

Header File: GPU_raster.h

Switching 

void GPU_raster_begin(void);
void GPU_raster_end  (void);

Feature Flags 

typedef enum GPURasterShaderOption {
	GPU_RASTER_STIPPLE = (1<<0), /* polygon or line stippling */
	GPU_RASTER_AA      = (1<<1), /* anti-aliasing             */
	GPU_RASTER_POLYGON = (1<<2), /* choose polygon or line    */
} GPURasterShaderOption;

OpenGL Replacements
