Detailed Description

Linear map from layout pixels to whatever space the vertices are drawn in.

lay_out() places glyphs in pixels with y growing downward. A map takes such a point to output space as origin + pixel * scale, so one set of quads can be drawn in NDC, a world plane or any other space by choosing the map. Glyphs land on whole output pixels when scale is one pixel of that space and origin lies on a pixel boundary.
