Description
Certain users need to draw custom-generated content as the background of certain HTML elements. (For example, a dynamically generated mini-map drawn to a framebuffer on the GPU with floating indicators drawn with HTML)
We should add API so that users can declare a custom, sized image-source in HTML and query its texture handle in C++ so that users can draw to it on the GPU. (Also need to add API to force a View to repaint in case this custom image-source is updated)
