[processing] Accept strings of form "(1,2") for point parameters too
Browse files Browse the repository at this point in the history 
Since the help text above a point parameter indicates the acceptable
format is "(x, y)", it can be confusing for users to know whether
the brackets should be entered here. So be forgiving and accept
strings with or without brackets.
