Description

Looking at the gl driver code for drawing primitives, it appears everything is rasterized in software, and then OpenGL is only used to draw the resulting rasters to the screen. Since there is an OpenGL dependency anyway, why not use OpenGL to draw the primitives? It must have been considered. Is it something planned for the future? Are there strong reasons not to?

Contributor guide

Research direction
Investigate the current software rasterization implementation and compare with OpenGL based rendering for canvas primitives. Look into the gl driver code and consider performance and design trade offs.
