/**
* @experimental
* Geospatial camera inputs can simulate dragging the globe around or tilting the camera around some point on the globe
* This class will update the GeospatialCameraMovement class's movementDeltaCurrentFrame, and the camera is responsible for using these updates to calculate viewMatrix appropriately
*
* As of right now, the camera correction logic (to keep the camera geospatially oriented around the globe) is happening within the camera class when calculating viewmatrix
* As this is experimental, it is possible we move that correction step to live within the input class (to enable non-corrected translations in the future), say if we want to allow the camera to move outside of the globe's orbit
*
* Left mouse button: drag globe
* Middle mouse button: tilt globe around cursor location
* Right mouse button: tilt globe around center of screen
