viewer: add colour theme support #213

Open abey79 opened 3 years ago

abey79 commented 3 years ago

In a first step towards better colour support and to address abey79/vsketch#51, colour "themes" should be added to the viewer:

a "theme" would have a name and contain a background colour + colours of the N first layers (layers > N have the colours of their modulo N)
a few themes would be included by default ("standard", "cmyk", "black")
additional themes could be defined in ~/.vpype.toml
theme would be selected from the layer "button menu" in vpype viewer
selected theme would be remembered across vpype instantiation

What this issue explicitly doesn't cover:

adding colour metadata to vp.Document
reading colour from input SVG (#35)
setting colours of output SVG (#145)

This is better covered by #359
