Add an option to change the first segment (node) #174

Open eliheuer opened 3 years ago

This option could just be something in the paths menu with a label like "make selected node first".

This would be useful for a variety of reasons, but mainly it is important for variable fonts. If two paths have the same point structure, but different first segments, the interpolated in-between shapes will be twisted and unrecognizable.

Maybe I could figure out a PR for this using src/draw.rs/draw_direction_indicator as a starting point.

This is a good feature to have. One question to resolve is how it's invoked. Glyphs seems to surface this primarily through a context menu, which is possible but I think involves some more hit-testing logic to figure out if the right-click is on a point. An easier possibility is "make selected point first," but this is only going to be meaningful when there is one point selected. (Or, more generally, one point per contour)

We need to do better context menu stuff anyway, so this could be a good excuse for that.

My first instinct is to select a node and right-click on it looking for a context menu. It would be nice if “reverse contours” from the Paths menu was in the same section of the context menu as well.
