View cube hover lights the whole region a click turns to: a corner its 3 patches, an edge its 2 strips, a face its middle (one hit test for hover and click; test over all 26 regions). View animations ease with smoothstep and take longer for turns past a quarter turn, so no frame sweeps much more than 9 degrees; s38 and s39 enabled

Fixes #15
