fix: Use differential rounding for consistent inter-glyph spacing ( #1413 )
...
**What is the goal of this PR?**
A tweak to the fixed-point x-advance and kerning calculations to ensure
that the spacing between any two glyphs is always calculated
consistently.
I noticed that sometimes I'd see common character pairs like "oo" more
than once on a page, and the distance between the two snapped to
different pixels depending on the running accumulated error for the line
of text.
This change uses a differential rounding approach where each glyph's
x-advance plus the kerning relative to the next glyph are combined in
fixed-point precision, then snapped to a pixel to draw the next glyph.
This results in a consistent inter-glyph spacing any time the same two
glyphs show up adjacent to each other, regardless of the accumulated
error across the line.
