⚠️ Removes `Context::translate_layer`, replacing it with a sticky `set_transform_layer` Adds the capability to scale layers. Allows interaction with scaled and transformed widgets inside transformed layers. I've also added a demo of how to have zooming and panning in a window (see the video below). This probably closes #1811. Having a panning and zooming container would just be creating a new `Area` with a new id, and applying zooming and panning with `ctx.transform_layer`. I've run the github workflow scripts in my repository, so hopefully the formatting and `cargo cranky` is satisfied. I'm not sure if all call sites where transforms would be relevant have been handled. This might also be missing are transforming clipping rects, but I'm not sure where / how to accomplish that. In the demo, the clipping rect is transformed to match, which seems to work. https://github.com/emilk/egui/assets/70821802/77e7e743-cdfe-402f-86e3-7744b3ee7b0f --------- Co-authored-by: tweoss <fchua@puffer5.stanford.edu> Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>
