Implement subpixel glyph positioning and scaling

Browse source 
The latest `cosmic-text` release performs bucketing calculations after
layouting. This allows us to provide proper subpixel offsets, as well as
scale any buffer thanks to its linear layout properties.

See https://github.com/pop-os/cosmic-text/pull/143.
