* Thorben's transformation (rotation/mirroring) of viewports.
* New buttons in the HUD for rotation and axis swapping.
* Refactoring of sliceSelectorHud.py to remove code duplication and drawn icons.
* Thin position markers corresponding to size of brush.
* Standardization of icon usage using PyQt's resource system.
