Investigate the 2x2 map size myth #1411

Open sprunk opened 4 months ago

sprunk commented 4 months ago

Maps with odd lobby size edges (eg. 13x13) don't seem to exist in the wild but I have never seen anybody give any concrete reason why that would be.

Tasks:

compile an odd-sized map. Doesn't have to be actually playable, just needs to run. Try a bunch of sizes, say 13x11 (both edges odd), 13x12 (one edge odd), 1x1 (maybe 1 is haram?), 1x2. This is the "good first issue" part.
if something breaks, figure out why and fix.

@Beherith mentioned that the map texture sizes needed to be at multiples of the 2x2 map size. As a result I've put that restriction into QTPFS as well (which is easy enough to change)

Ideally somebody would point a finger at this assumption in the relevant code snippet.
