Feature Request: Fill ggridges with Images

[hunterkempf]

My Feature Request is to make the fill "color" of the ridges into an image. The idea is similar to this repo (flags on country shapes) or this repo (images split by line charts or bar charts). I am not sure how hard it would be to incorporate but I think it has the potential to make some cool graphics especially with country level data.

• FYI: I think this should be possible now after feat: Support grid::pattern() / gradient fills #98
• You need R 4.2+ and ggplot2::check_device("patterns") must be TRUE in your active graphics device i.e. the newish pattern fill functionality must be supported by your graphics device.
• You could manually wrap the image in grid::rasterGrob() and then in a grid::pattern() object or perhaps alternately use gridpattern::patternFill("image").

Yes. Here is a long tutorial on pattern fills: https://wilkelab.org/dataviz_shortcourse/materials/positconf2024-pattern-fill.html

This should work now with the development version of ggridges, though I haven't tried.
