Module PolyTextSource

Point path representations (using Poly2.t) of text via ocaml-cairo import of system fonts. NOTE: Still somewhat experimental.

Ideally, the point representations obtained from fonts here should make it simple to produce rounded text extrusions. Unfortunately, the story there is somewhat fickle at the moment due to diffculty in applying roundovers/offsets to the paths produced, in part due to the tight point spacing and sharp corners that they can have. Thus, this module may evolve to make use of OpenType variable fonts to produce the offset paths required (via variable weight).
