fixed @memononen any chance of a merge?

@wheybags also it would be super useful to be able to provide two different text sizes: one for glyph size under SDF font and another for actual text size. Because SDF fonts don't really work that well under small pt sizes.

@jimon What I do is pass in a constant value to fonstash (30px), and then scale the font metrics I get back according to the difference between the constant and the actual size. I also scale the resulting vertex buffer.
