gradient line not changed immediately when lens correction is activated/deactivated

extracted from #10139

Reproduce: with lens correction on (resp. off), a gradient line is curved (resp. straight); activate (resp. deactivate) lens correction: the gradient line doesn't change, while it should (this is the bug), but as soon as you begin moving it, it gets straight (resp. curved).

The line should change immediately when the lens correction is activated/deactivated.

Confirmed. We need a way to update the mask overlay when the pipe is recomputed. Not that it's "just" a drawing glitch : the image itself is updated with the correct gradient line.
