Description

Hi. It's cool to create custom shapes (Shape objects) with Plots, which can be used to draw creative figures (like the Batman example in ExamplePlots), or as new markers, for instance. I would like to know if there is some way to create such shapes with "holes", e.g. a ring, which would be like two concentric circles, but with the smaller one "removing" part of the filled area.

Contributor guide

Research direction
Explore how custom shapes are rendered in Plots.jl backends (e.g., GR, PyPlot). Look for support for polygon holes via the even odd fill rule or by defining sub paths. Then propose a method to add holes to Shape objects.
