Feature RequestL msdfgen 1.4

[neurolabusc]

This is a terrific tool. As a feature request, it would be great to upgrade the msdfgen binaries to version 1.4. I can not find documentation on how to compile msdfgen on MacOS, but you did this with the older version. Hopefully you can do the same with the modern version. I have noticed a few artifacts with this older version of msdfgen when gneerating lower-resolution bitmaps.

Hey @neurolabusc, could you try this branch and let me know if it works for you?

It seems to invert my test case font, weird.

[neurolabusc]

Nice. You just need to change your shader for the new format, as shown on the msdfgen web page. This makes a huge difference in reducing artifacts when the font bitmaps are created with a low resolution or when normal sized bitmaps are scaled to be small.

Hmm, the new shader almost works, but I get rendering artifacts around the edges of my glyphs. Any thoughts? I've updated the msdfgen1.4 branch.

[neurolabusc]

My solution was to increase the "x" position by 1/scaleW, the "y" by 1/scaleH and the decrease the width and height by the same amount, but this is a change with respect to how they are represented by Hiero. So perhaps the change could be put into the generator. I think the truth is that with Hiero's standard distance fonts the edges of the quads have no information (they are very distant from the character), but with the new version of msdfgen the hinting extends right to the border of the character's quad.

Any updates on this? Have the artifacts been resolved?

[arilotter]

@gigablox a PR is in progress by @soimy here: #15
I'll get to thoroughly reviewing and probably merge in a couple weeks, but you can use the WIP branch for now if you'd like updated binaries sans-artifacts
