App 2.40.2: the Grid map moves on the GPU

The map was hardware-rendered, but every frame recomputed every road
point, rebuilt every path and drew the big roads three times, at 20
frames a second, and the car jumped with each GPS fix. Now it is its own
view under the Grid (MapLayerView, a hardware layer): drawn once into a
GPU texture and only redrawn when tiles change or after about 230 m;
each display frame only sets its translation and rotation. The car
glides between fixes, and the Grid over the map redraws only with the
readings.
