| -// | 
| -//  A class that determines the best new size and position for a window to be | 
| -//  shown at based several factors, including the position and size of the last | 
| -//  window of the same type, the last saved bounds of the window from the | 
| -//  previous session, and default system metrics if neither of the above two | 
| -//  conditions exist. The system has built-in providers for monitor metrics | 
| -//  and persistent storage (using preferences) but can be overrided with mocks | 
| -//  for testing. |
