NewModifyProp

ModifyProp(), but with selective refresh.

Performs the function of ModifyProp(), but refreshes gadgets in the list as specified by the NumGad parameter. With NumGad = -1, this function is identical to ModifyProp().

New for V36: When NumGad = 1, this function will now perform an incremental update of the proportional gadget knob image, rather than refreshing the entire gadget. This means much less flashing when programmatically scrolling a proportional gadget.
