This included half the game state and lots of unneeded parts of the software renderer.
The two modules that are shared between softpoly and the classic software renderer have been moved to a neutral place.
Vulkan hardware buffer for software canvas may have some padding
Software renderers should be aware of buffer's pitch in order to copy pixels properly

These can cause highly dangerous recursions and execute play code deep inside the renderer and since the hardware renderer does not have these, there is very little point for the software renderer to retain them.
