ngl: Improve the glyph front cache

The effectiveness of the front cache is limited by
subpixel positioning making it very likely that we
will meet the same glyph in  different x phases inside
a single line of text.

Factoring the xphase into the front cache key makes things
better. For the string eeeeeeeeeeeeeeeeeee

before: 0% front cache hits
after: >90% front cache hits
