This is the code in SkiaFontWin.cpp. That's non-ideal, and it would be
better to have Skia get the outlines itself and use the Skia path. I
don't actually know where the rounding problems occur on Linux. Skia
should be fine with it, but its probably in the way it interacts with
FreeType (maybe a glyph cache that requires being pixel-aligned?)
