Fix brush cursor size with canvas rotation #1869

Closed scribblemaniac closed 2 months ago

scribblemaniac commented 2 months ago

When rotating the canvas, the brush cursor displays the wrong size. This was because mapRect is used, which will expand the size of a QRect to fit the bounding box of a rotated rectangle. This fix manually applies the view transform to the rect by translating the rect (based on the view translation, scale and rotation) and scaling the rect size without actually rotating the rect.

Fixes #1868.

This works perfectly, even when the view is flipped! Thank you so so much! 😄
