P: Brush, Clone, and Heal brush shape options (squares and/or rectangles)

I'd like to see different shape options for the Adjustment Brush and Clone/Heal tools. Circles don't work to well on linear objects. I'd like to see squares. If it doesn't require a great deal of additional code-writing, I'd like to be able to rotate and change the size of the square brush. Just a thought.Jimwww.JMartinHarris.com
