Subject: I was too agressive in the fg_os port.  Glut doesn't support grabbing
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=95e8b639883a6f4d61ba48a5f4fa0ed80446d353;p=flightgear.git

I was too agressive in the fg_os port.  Glut doesn't support grabbing
the keyboard modifiers outside of a key event handler, so adding the
fgGetKeyModifiers() call to doMouseMotion was broken.  The user could
see "phantom" modifier keys.
