bPoint Relative Coordinates

[connor]

This might be a stupid question...but why are bPoint coordinates relative to the bPoint's anchor location and not within the glyph's overall space?

Thanks,
Connor

Thanks for the explanation, @colinmford! These relative/absolute functions are super helpful.

I believe it's to do with the idea of a bPoint being one "thing", the handles are a part of it.

In the point object, each point is separate, with absolute coordinates.

Also FontParts has a few methods to deal with the conversion between relative and absolute if you need em.
