Subject: [PATCH] Fix for #2327 Mouse pointer moves to centre of canvas on
 click in OpenGL3 with Swing Modify FlyByCamera to only hide the mouse cursor
 when the user actually rotates the camera, rather than when the user first
 presses the left mouse button. When the mouse is clicked, instead of
 immediately hiding the cursor, a flag (hideCursorOnNextRotate) is set. If and
 when a rotate is detected, the flag is checked and if true the cursor is
 hidden and the flag is cleared.
