170 works on this issue

simplylizz commented 2 months ago

Hello,

Is there any chance that #170 will be merged soon? I've managed to use polybool for the same purpose, but to be honest converting between two libraries is quite annoying and also, polybool doesn't support directly multipolygons, so I need to union them first, what is also could be a resource-consuming operation and by some reason doesn't always work well.

@simplylizz the functionality is mostly ready except for some testing. See #170. that branch could already be used.
