2021-10-14	Texture mapping!	tslil clingman
	We already calculate almost everything we need if we want to map textures per line segment v[i]->v[i+1] for v the list of vertices per cell.
2021-10-13	Polygonal walls!	tslil clingman
	It was essentially working before, just some indexing bug.
2021-10-12	It almost works, but for some reason everything only has 3 sides...?	tslil clingman

2021-10-12	Merge branch 'main' into polygon_walls	tslil clingman

2021-10-12	More texture bugs, hoorahHEAD main	tslil clingman
	Might as well also compute texel_y directly like texel_x for objects and skip a multiplication in favour of addition
2021-10-12	No need to recalculate the index inside each loop	tslil clingman
	Here's hoping Zig is smart enough (TM) to constant-ify all of these @floatToInt(type, PlaneXXX) values.
2021-10-11	Fix many texture bugs, access memory in increasing order everywhere	tslil clingman
	- 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
2021-10-10	Untested first mock up of polygon intersection in square	tslil clingman

2021-10-10	Refactor: extract rendering code from Player struct into Renderer	tslil clingman
	Some bonus off by ones and rounding corrections
