Tweak distance field path renderer behavior in gamma-correct mode to match
recent changes to text rendering.
Uses linear coverage falloff. Produces results that are perceptually more
similar to L32 (raster and gpu). Smoothstep + sRGB was too soft.
Plumb the gamma-correctness via DrawPathArgs, which also paves the way for
other path rendering implementations to easily make decisions about rendering
technique based on that flag.
Fix a few typos and formatting issues from my most recent change.
