Zoom - zoom step - add custom levels

[user0]

XnViewMP 1.12.2
Windows11 (26H2), display resolution 3840x2160, win scaling 150%

Viewer / Browser-preview
there are few requests to limit zoom levels like in MS Photos or Lightroom, CaptureOne, but I would start with simple custom steps
Limiting zoom out
Limit zoom in fullscreen

Suggestion
