Acrylic is a work-in-progress user interface toolkit.
As-is, this library can only render elements to an in-memory pixel buffer or png files. We aim at supporting webassembly and linux framebuffer platforms before Q3 2022.
It is a planned feature. You would be able to add nodes to the tree based on an xml file which would represent your UI. This would result in a system very close to how web pages are handled in web browsers.
