raycast: initial distributed implementation
The main task runs on processor (0,0,0). It manages game logic and
initialization, and participates in the rendering process.
The render task runs on all other processors. It tries to render a frame
slice when available, which is raycasting + pixel drawing for a pixel
column of the frame.
