cleanup Draggable into ResizingAnchor (#989)
* Rename `Draggable` as `ResizingAnchor` since that is what it is used for and shouldn't be mistaken as a general draggable item * Refactor `ResizingAnchor` to be much more smart about how it handles mouse movements. Allow it to know which direction the resizing should be in allowing it to produce exact resized values. * Add event handlers for the min and max extents so that actions can be triggered when those extents are passed (in either direction) * Add double click support Signed-off-by: Sebastian Malton <sebastian@malton.name>
