Little painting (1x1 and 2X1) are correctly placed in hologram. Bigger are misplaced.

litematica 0.0.0-dev.20190630.024955 and 0.10.0-dev.20

Schematic:
painting.zip

This is an unfortunate vanilla bug. I noticed this myself a while back and tried to debug where the bug is in Litematica, but this does actually also happen with the vanilla Structure Blocks, when you load the structure in another location, the big paintings are offset.

So basically I'll have to add a fix for the vanilla painting code itself to fix this, assuming it's even feasible to fix, but I'd think it should be.
