Add ATC callsigns.
Add ATC mode, displaying basic info for all aircraft.
Add airport range rings.
Change Device setting to be an AM Demod setting, so AM demod isn't at DC.
Add basic aircraft data to ADSB Web API report.
Allow OpenSkyNetwork DB, OpenAIP and OurAirports DB stuctures to be
shared by different plugins, to speed up loading.
Perform map anti-aliasing on the whole map, rather than just info boxes,
to improve rendering speed when there are many items. Add map
multisampling as a preference.
Add plotting of airspaces, airports, navaids on Map feature.
Add support for polylines and polygons to be plotted on Map feature.
Add support for images to 2D Map feature.
Add distance and name filters to Map feature.
Filter map items when zoomed out or if off screen, to improve rendering
performance.
Add UK DAB, FM and AM transmitters to Map feature.
Use labelless maps for 2D transmit maps in Map feature (same as in ADS-B
demod).
(Possibly need to add a mutex for MainCore::getPluginManager, so only
can be used by one thread)
Add option to automatically update My Position based on GPS. This is
started in MainCore, so we get position as soon as possible.
Don't set QFileDialog::DontUseNativeDialog on Android, as Qt's file
dialog can't access user storage. Set globally for Linux/Windows, rather
than for each dialog.
MainWindow:
- Add welcome dialog for Android.
- Don't show menu bar or status bar on Android to save screen space.
- On Android, change tab position when screen orientation changes.
- Load default configurations and presets first time SDRangel is run.
- Change loadConfiguration to use a QProgressDialog rather than
QMessageBox, as the latter was crashing on Android.
- Use DialogPositioner to ensure dialogs are on screen.
