It would really help, if xfcalendar remembered the window position at the time 
when the main window is closed and then showed exactly in the same position 
altered by desktop edges/screen size.
It would be much more convenient than show in 'random' position, what happens 
now.

Reproducible: Always
Steps to Reproduce:
1. open xfcalendar window
2. move the window in another position
3. close the window
4. open it again
Actual Results:  
The window shows in the position as in step 1

Expected Results:  
The window should open in position after step 2
