Description

Anonymous Pro from http://www.marksimonson.com/assets/content/fonts/AnonymousPro-1.002.zip
does not render at point sizes below 13.5. Some glyphs render a couple of stray pixels but most stay completely empty.

Renders fine in Firefox and other applications though...

Research direction

Reproduce the issue in font-kit on Linux with Anonymous Pro at point sizes below 13.5, then trace the FreeType rendering path used by the Rust library. Done means the font's glyphs render correctly at those sizes, matching the behavior reported in Firefox and other applications.
