Calculate geographical coordinates(i.e., longitude-latitude pair) that corresponds to screen coordinates.
The screen coordinates are in MapOptions.size platform pixels relative to the top left of the map (not of the whole screen).
Map must be fully loaded for getting an altitude-compliant result if using 3D terrain.
Returns a batch of geographical coordinates corresponding to the screen coordinates on the screen.
A batch of screen coordinates on the screen in MapOptions.size platform pixels.
