Expected Behavior
There should be a way to specify the color of the text being drawn.
Current Behavior
opentype.js is the Henry Ford of font rendering "Any [user] can have [their text] any color that [they want] so long as it is black."
Possible Solution
Allow a color to be selected in the draw call for Font and Glyph objects.
Context
My library has to manually draw the path to work around this, granted I have to do this anyways as I need to stroke the text too, but my point stands.
