Zoom 12: GlobeView switches from GlobeViewport to WebMercatorViewport, and deck.gl's flat projection switches
from WEB_MERCATOR to WEB_MERCATOR_AUTO_OFFSET. Side views: the north-south plane through the map center seen from the
east, at the same scale in every panel. Each build's camera and target come from its own deck.gl viewport. The trace is
the camera over the zoom range, red dashes mark a jump. Measured terrain: the surface each
build draws, picked with unproject3D along the center column of its view, in orange over the elevation
data. Renderer of this browser:
