Feature request: enable color aesthetic on Geom.label

[amellnik]

It's not just that I would like to plot a rainbow mess of emoji, but also that this gives us a way to make simple scatter plots with more than one symbol.

This would break some existing plots that are currently using labels in the same layer as a Geom that uses color like

plot(dataset("ggplot2", "mpg"), x="Cty", y="Hwy", label="Model", color="Drv", Geom.point, Geom.label)

but it could still be done with two layers. If this seems like a good idea I should be able to put together a diff.

This would be a nice thing to have. My main concern is that text will be illegible with some colors. Maybe the way to go is to add an ignore_color parameter to Geom.label that defaults to true.

i hope this gets resolved soon.

I started to look at this, but ran into GiovineItalia/Compose.jl#348 i.e. there's an issue with the fill property for svg text in Compose.

Any progress on this?!

I'm wondering the same.
