The last two settings are designed to be used while zooming with the Mouse Wheel or
trackpad.

Zoom+Pan within visible area – if this setting is on, then the panning will take place inside the
area visible before the start of the panning. If it is off, then the panning will be over the entire
image.

Zoom anchor at mouse cursor – zooming will happen taking the position of the mouse cursor
into account; the point underneath it will retain its position respective of the window during
zooming.

Use Logical pixels for zoom calculation (Mac OS X only):
o If turned on (default, "legacy" behavior), then the pixel in the screen is considered to
be the "logical pixel" (in the case of Retina, it's a block of 2x2 "physical" pixels) and the
calculation of the zoom size is done in these units.
o If turned off, the zoom value is calculated in "physical pixels", so for Retina screens the
displayed zoom value will now be doubled, and at 100% zoom the image will be half
the size compared to "legacy" behavior.
