In Sketch I have some guides I've placed. When I draw shapes (let's say a rectangle) they automatically snap to the guides when the mouse cursor is a few pixels close to those guides.
How do I "snap to guide" the selection while editing a bitmap? (to edit a bitmap, just drag&drop a bitmap image in Sketch, double-click on it, and then click&drag to select a rectangular shape)
