tile layer offfset value doesn't work in infinite map

[NO-MEANINGS]

in tiled:

in love:

how to reproduce the bug:
create a new map with property infinity checked.

create a new tile layer and set some offset value. don't forget to put some tiles on layer.

draw the map in love, and you'll find the offset value doesn't work.

possible cause of the problem:
line 504 in init.lua: local offsetX = chunk and chunk.x or 0
line 505 in init.lua: local offsetY = chunk and chunk.y or 0
It seems that the method of calculating the offset value is wrong. I’m not sure since I’m new to programming. XD
