commit 5580b5e80e8a9a9973099a5fa3fe9fc91d25726d
Author: Peter Clifton <pcjc2@xxxxxxxxx>
Commit: Peter Clifton <pcjc2@xxxxxxxxx>

    hid/gtk: Fixup Zoom() and zoom_by() so they don't ignore passed coordinates.
    
    The Zoom() action was passing bogus coordinates (in pixels), and
    zoom_by() was ignoring the passed coordinates and just using the mouse
    pointer location last recorded in gport->pcb_x and gport->pcb_y.
    
    Fix zoom_by() to use the passed coordinates, fix Zoom() to not mangle
    the passed board coordinates into screen space.. zoom_by() wants
    board coords.
    
    Finally, remove a special case from the Zoom() action where if the passed
    coordinates were both zero, we would pass the PCB coordinates of the board
    center. I'm hopeful that things will "just work" without this.
