interactive: allow moving horizontally/vertically maximized window

Browse source 
Applies drag resistance unidirectionally for horizontally/vertically
maximized windows, allowing them to be dragged without being untiled
immediately. When the distance of cursor movement orthogonal to the
maximized direction exceeds <resistance><unMaximizeThreshold>.

While dragging a horizontally/vertically maximized window, edge/region
snapping is disabled to prevent unintentional snapping and overlays.

This commit also includes some refactoring to simplify the logic.
