Image Overlay for Multi-Color Prints

I’m proposing a Sticker Mode for PrusaSlicer that would allow users to apply 2D images or graphical overlays directly onto the surface of an already created 3D model. The slicer would then convert these stickers into either multi-color printable sections or colorable outlines that users could manually assign to selected materials. This feature would enable easy customization of models—such as adding logos, patterns, labels, or simple graphics—without requiring advanced graphics/modeling skills.
