Simple TTF fails to render with distance field...

Check out the attached font. When rendering in QML I get warning spew as below and the text doesn't render. If I disable distance fields, the font renders.

In looking at the code, it seems that perhaps qsgadaptationlayer.cpp doesn't handle cases where the font has a small subset of glyphs? Hard to say. This font only has some basic english letters and numbers in it.

Warning Spew:
