Thanks for report: it looks like QuickZoom+Pan works incorrect on vertical images, image position is calculated with non-rotated size in mind (so exact position is wrong). To be checked and fixed if needed.
For QuickZoom+Drag, the point clicked is centered to window, not placed under mouse pointer. To be examined too, may be it is better to keep it under mouse.
Zoom (by Wheel) with 'mouse pointer in mind' is in TODO list. May be we'll need to make it configurable option, not sure.
