note 14367 rejected from function.imagesetstyle by didou

Note Submitter: hatamoto@hhole.com ---- While this is far more flexible than the old imagedashedline() function, the older function had a desirable capability... namely, in between the dashes was transparent space where the existing image wouldn't be overdrawn. Is there a masking function for the style that I'm not aware of, or some way to make certain pixels transparent? If not, then I suggest that would be a highly useful addition. An alpha mask applied to the style array could come in handy in a number of places, imo.
