Orthographic Zoom II

Full Screen

An second attempt at panning and zooming with Orthographic projection. Improves upun the first attempt Orthographic Zoom I in that panning accounds for the latitude. So in this version, if you zoom into, say, Iceland, panning still has the right sensitivity, whereas it did not in the first iteration.

Still struggling to get pinch zoom and drag pan to both work on mobile.

Uses world-110m geographic shapes from TOPOJSON World Atlas.
