Subject: Reorganized software rasterizer as a module which manages its own state,
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd03ed4f54444d96e4e47cdb118a3dfd94d92bb0;p=mesa.git

Reorganized software rasterizer as a module which manages its own state,
with tighter interfaces with the rest of the world.

Proper documentation to come.

+ * Rasterization hardware drivers:

+ *   - Implement native twoside,offset and unfilled triangle setup.
+ *   - Implement a translator from native vertices to swrast vertices.
+ *   - On partial fallback (mix of accelerated and unaccelerated
+ *   prims), call a pass-through function which translates native
+ *   vertices to SWvertices and calls the appropriate swrast function.
