Fix many texture bugs, access memory in increasing order everywhere 2021-10-12T02:56:39Z tslil clingman 2021-10-12T01:55:39Z urn:sha1:b21e399bd09577d2eef78d81c0db642ba4c390b7 - switch z_buffer to use screen space coordinates (why does y increase downward!) - extract pointless (re)calculations from inside hot loops, in particular from object drawing but also to the extent allowed by applicable law from floor and ceiling drawing Refactor: extract rendering code from Player struct into Renderer 2021-10-10T20:00:55Z tslil clingman 2021-10-10T19:31:36Z urn:sha1:cb15709551921e111d2648f7d6545e4d0e3fdcd6 Some bonus off by ones and rounding corrections
