[Cuis-dev] Icons with path sequence in vector graphics

[Luciano Notarfrancesco]

Got it, in a few lines of code I can fully convert path data in that
compact standard format to a list of PathCommands, and then I can just
compose with a transformation for a given height and position and draw it.
Works great!
Juan, perhaps we should extend VectorEngine>>pathSequence: to support all
commands? Or your idea is to convert other commands to this reduced subset
(like converting arcs to a list of bezier curves I guess, etc)?
