DW -> IJ Conversion

[parnassian]

Hi guys! So there's a guide to convert IJ styles to DW, but I'm looking around and there doesn't seem to be any guide for converting the other way. I've made some progress but when I go in to compile my custom layer I'm getting a ton of errors. The current one is "can't declare usage of non-existent property" (property use layout_type; is the italicized line). I'm picking at it slowly but I thought I'd reach out to see if anyone has any experience with converting from DW to IJ and any finicky things I need to change in the raw code.

If it helps, I'm trying to convert Basic Boxes. Thanks in advance!
