At least support something similar to the COM API's GetPointOnTerrainFromScreenCoords
method.

Perhaps this limitation could be solved within this issue:

The range in the following function:

ge.getView().copyAsLookAt(ge.ALTITUDE_RELATIVE_TO_GROUND).getRange() 

doesn't take into account 3D buildings. It would be great if each point of each 3D
building could be an end point for getRange.

I totally agree with previous posts. This function (similar to COM
GetPointOnTerrainFromScreenCoords() function) is a "must have" to control navigation
with javascript code. Please, please, please... ;D
Best regards

As of API v1.003, plugin 5.1.3509.4636 GEView.hitTest is returning incorrect results. 

Hit tests at each corner of the viewport returns results well outside of the viewing 
area.

See issue 361 for a code example.
