Christoph Oelckers d30bf8c8bb - fixed Blood's mirror render hack for Polymost. 
This adds 4 walls and 1 sector without counting them, so we must adjust allocations and array access to handle OOB access and temporarily increase the counter for the mirror render pass.

The new renderer does not need this stuff.
