Changes between Initial Version and Version 1 of Ticket #16865, comment 15

initial	v1
1	1	I made the "xr on" command enable mouse and keyboard input on the Acer and Sony 3D displays.
2	2
	3	To select or pick an atom the mouse pointer needs to align with the object using the right eye. This is because the mouse events are mapped to the main graphics pane and it mirrors the right eye view from the 3D screen.
	4
3	5	This is done on the Acer display using a backing Qt window which captures the mouse and key events since the Acer OpenXR window passes those events through to the window behind. The Sony SpatialReality display OpenXR window captures the mouse and key events so on that display I make a transparent Qt windows that lies in front of the Sony OpenXR window to capture mouse and key events.
