9-Slice Image Scaling

Adreal

I would love to see support for 9-slice (3×3) image scaling in Lunacy. This would allow images or UI elements to be resized without distorting the corners and edges. The corners would remain fixed, edges would scale in one direction, and only the center area would stretch.

This would be especially useful for UI components like buttons, panels, and dialog backgrounds, improving workflow and preventing visual distortion.

(it may be also called Sub-Region(?))
