When implementing a symbol as an instance and overriding the "textWeight", Sketch stores/relays a value like this:
(for ArialMT -> Arial-BoldItalicMT in this case)
{ NSCTFontWeightTrait: 0.4,
NSCTFontProportionTrait: 0,
NSCTFontSlantTrait: 0.06666666666666667,
NSCTFontSymbolicTrait: 2147483651 }
It seems like it would be way more helpful for Sketch to just relay the postscript name that this is all based off of in a plugin ecosystem, so that it can be easily converted to non-Apple apps or the web. In lieu of that, is there a reasonable way to convert these to a postscript name using the Sketch APIs?
