It was only used to fetch resY, so I replaced that by taking the y-coordinate as an argument. That is also more consistent with the x-coordinate which was already an argument. The x-coordinate was changed to a signed int, since that is the norm for paint coordinates. It can be useful for drawing widgets that are partially off screen, for example during a (dis)appear animation. In InputDialog, the ButtonBox field was changed from a pointer to a plain data member. There was no need to dynamically allocate it.
