Zoom level boundaries

Maximum zoom level and minimum zoom level allow you to set the most zoomed-out and most zoomed-in state which the mouse wheel will allow to zoom-in or zoom-out.

The intention is to not need to load all (big) sprites for a certain zoom-in level or not run into a lag on evolved games by preventing to accidentially zoom-out more than usually intended.

Possible Settings:4x, 2x, normal

In Openttd.cfg config file: [gui] zoom_min = <0-2> (0=4x, 1=2x, 2=normal)

Possible Settings: 2x, 4x, 8x

In Openttd.cfg config file: [gui] zoom_max = <3-5> (3=2x, 4=4x, 5=8x)
