/**
 * @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
