Prusaslicer: Cannot zoom properly with retina resolution in 2.3.0-alpha

[mathiasvr]

Version

2.3.0-alpha2

Operating system type + version

macOS Mojave 10.14.6

Behavior

• _Describe the problem_
  When using retina resolution for the 3D scene you cannot zoom when the cursor is placed in an area spanning twice the size of the legend view such as feature type, speed, etc.

• _Steps needed to reproduce the problem_
  With retina resolution on mac, place the cursor left or below the legend and notice how scrolling is active in the legend and not zooming the scene when placed up to 2x the width or height of the legend.

• _Expected Results_
  Scrolling should only be active for the legend when the cursor is placed in the visible area, and otherwise be zooming the scene.

• _Actual Results_
  Scrolling affects the legend and not the scene when the cursor is inside an area covering twice the visible legend, as marked by the red square area below.
