SelectionGeometry class

The geometry of the current selection.

This includes details such as the locations of the selection start and end, line height, the rects that encompass the selection, etc. This information is used for drawing selection controls for mobile platforms.

The positions in geometry are in local coordinates of the SelectionHandler or Selectable.
