[Request] Use Images for Bars
MapTool has an option that allows you to use an image for a bar -- if you use a single image, it removes part of it proportionally. You can also set a "background" image, so that you have a bar that gradually reduces from one version to the other, or set it so that each increment or portion gets its own separate image.
This would allow you to have a custom bar that has a color gradient in place, or one with a decorative border. Some MapTool modules even use a curved image with transparency, so that the bar lines up with the edge of round tokens.
You can see the full list of options they have on their wiki page on bars, and it would be nice to have the same capability in Foundry.
