P: (Masking) Geometrical shapes as masking option

I propose adding geometrical shapes, like rectangle and ellipse, as methods in Create new Mask. 

Reason: The current methods are good when improving photos. But sometimes there is a need to redact or emphasize an object and make that change obvious to the viewer. Geometrical shapes with sharp edges work better in these cases. The brush with shift-click provides a workaround on computers but painting free-hand on a touch screen usually produce an unprofessionally looking result.
