Change how anchor name value is gotten

[benkiel]

This should account for getting a value that doesn't exist in a math glyph, addressing #678

[typemytype]

the anchor.name attribute is optional according the spec, so is anchor.color, this could also be changed to anchor.get("color")

[benkiel]

Agree, changed. Still not going to solve @LettError's problem, unfortunately

[justvanrossum]

But look how toMathGlyph always sets name and color:

fontParts/Lib/fontParts/base/glyph.py

Lines 1641 to 1649 in f5250dc

	for anchor in self.anchors:
	d = dict(
	x=anchor.x,
	y=anchor.y,
	name=anchor.name,
	identifier=anchor.identifier,
	color=anchor.color
	)
	mathGlyph.anchors.append(d)

I don't quite understand what "the spec" (which spec?) has to do with this.

@justvanrossum UFO Spec: https://unifiedfontobject.org/versions/ufo3/glyphs/glif/#anchor

[LettError]

Would like to test, but how do I get this code to run locally?

UFO Spec

Perhaps I'm nitpicking, but what I mean is, this is just an object implementation, and it can decide by itself whether it demands those attributes to exist or not. Perhaps it requires the "missing" attributes to be substituted by None. The spec specifies the format, not how objects should be implemented.
