Before this change, the mouse-wheel click was equivalent to moving the mouse
pointer 120 pixels, where 120 is the hard-code constant for a single mousewheel
click event. There were two problems with this setting:
The effective zoom scaling factor was dependent on the screen size.
The smaller the screen, the larger the scaling factor.
Most of the time, the scaling factor was too coarse.
