Add sizeToContents in ChannelGUI and FeatureGUI, called when widget is
rolled, so we can remove resizing code from all of the individual
channels and features.
In RollupContents, use minimumSizeHint for calculated size, so that
minimumWidth can come from .ui file.
In DeviceGUI::sizeToContents(), call adjustSize(), so Device GUIs start
out at minimum needed size (which should restore appearance prior to
last patch).
In stackSubWindows, use available space for channels if no
spectrum/features present.
In stackSubWindows, fix spectrum from being sized too big, resulting in
scroll bars appearing.
Reset user-defined channel width in stackSubWindows, when channels are
removed.
Don't stack maximized windows.
There's one hack in Channel/FeatureGUI::maximizeWindow(). It seems that
when maximimzing a window, QOpenGLWidgets aren't always paint properly
immediately afterwards, so the code forces an additional update. I can't
see why the first call to paintGL doesn't work.
Add support for replaying of passes in the past, where current time is
determined from File Input device.
Add latitude and longitude to satellite data table.
Update ground track generation to better work with 3D map.
Add support for 3D models.
Add Cubesat image for 2D map.
Send LOS to other plugins, when no device settings are setup.
Pass TLEs to other plugins, so they can use a consistent copy for
replays.
