* Crop tool: Content-Aware fill of the area a rotated or extended crop uncovers (#3823)
image.crop gains contentAware (bool, default false). After a turned crop or one that extends
past the canvas, the area the original image doesn't cover is filled from its surroundings on
the Background (else the active pixel layer), in the crop's one undo step. Each connected piece
(corner, edge strip) gets its own Content-Aware sampling window and samples only covered pixels;
the patch search is Edit > Fill > Content-Aware's (fill_cmds::content_aware_native, shared). A
crop that uncovers nothing is unchanged; one with nothing to sample from fails and rolls back.
Crop options bar: Fill: Background (Default) / Content-Aware Fill (ToolOptions
crop_content_aware, ui.set cropFill). Generative Expand is not offered.
