Runtime 2.2.1.287+ breaks font loading for sprite fonts

[glitchroy]

The changelog for runtime 2.2.1.287 states:

• Asset Compiler
  • Sped up constructing texture pages from texture groups
  • Handling of cropped textures has been improved

(source)

This breaks the glyph data scanning in scribble_load_fonts() (at line 126 and following). Looking at the generated cache files, it seems that the TexturePageEntries for the font sprites now all generate with a 1px transparent border around them, regardless of texture page settings.
This causes the fonts to look jagged and cut off, probably because the sprite file is bigger than expected.

Downgrading to runtime 2.2.0.261 fixes the issue for now.
