Color mode's colours now come from a Palette (`palette` in imageTrace.make's
params), shown in the Image Trace panel under Mode:
- Limited: the `colors` best colours (what Color did before; the default).
- Full Tone: median cut until no colour box spans more than 96 (Less) … 8
(More) levels per channel, up to 256 colours, set by `colorDetail` 0-100
(the panel's Colors slider for this palette).
- Automatic: flat art (90% of the pixels in a few tight colours) traces with
exactly its colours, anything else as Full Tone.
- Document Library: the most used (at most `colors`) colours of the
document's swatches or of a swatch library (`library`: "document" or a
library id or name, chosen in the panel's Library list), used as they are;
traced shapes fill with the swatch's own colour, its colour model kept.
The library's colours are looked up at every trace, not saved.
