Yes, I've been thinking about this myself. It is possible to take small sections of a bitmap, or even individual pixels, and create a new bitmap from them using SM components. So a circular area could be "scanned" into a new knob bitmap with transparent 'edges'. Certainly, simple shapes like circles, triangles could be done.
Doing this uses a lot of CPU power, but, the moving parts only need "creating" once, when a new "master" bitmap is loaded - so it need not be a problem. The small sections will be remembered inside the schematic, and don't need re-making even when saving/loading the plugin.
