Improved C64 multitasking kernal raster code for new 3D petscii engine to make polychrome PETSCII raycasting more colourful and detailed. Could only test simple possibilities as too many configurations and the more complex ones like shadows, atmospheric and other effects take too much time at the moment to test So should look even better when get around to it. However many other things to do in the interim first....

Updating an old C64 3d PETSCII engine made years back into a hybrid raycasting engine which multiplexes a dual vector GFX bitmap overlay.
Hopefully looks nice and colourful like the Atari 800XL(see polychrome testing).
Hopefully can make a C64 Elite/Wolfenstein hybrid or some else entirely with the dual gfx engine.
Will probably work on off randomly over next few months. Lots to do so little time...
