I see a number of limitations. You hard code the size of the pattern,
rather than deriving it from the size of the design elements. Then I
see things like
For j = 0 To 3: For i = 0 To 3 + j
So you have to make 22 separate copies of the pattern in order to
ensure there are no gaps. A bit excessive, don’t you think?

Which is something I thought I made clear I was trying to get away from.

I think you are looking at a version which is already several hours old.
I was able to do complete coverage of the triwing tiling with just 7
copies of the pattern. Unlike your version.

You *did* see this in the README, did you not:
**WARNING:** This Python binding is still to be considered in a
state of flux for now, subject to whatever reorganization looks
to be necessary as experience is gained with using it.
