To answer some of my own questions...
1 - Some is in Compose.jl, but it's not all exposed, and I think I need the
lower level details so I am bumbling ahead.
2 - I've made things strongly typed as I suggested and then the Cairo.jl
naming became clearer - it omits nouns that are implied by type, I think,
which is what I had somehow changed into "pulling verbs to the front", so
names are now (with typed arguments) shorter and also more consistent.
But I still have no idea why \040 is appearing in some text.

PS git repo updated so following earlier links will show new code as I
linked to head.
