      At present, when map objects are being rendered, at each individual frame change of the camera data, the vertices and location of map objects such as polygons and circles is recalculated, a potentially expensive operation. It may be possible to re-use a previous rendering of an object during animation frames to avoid this re-calculation, by making assumptions about panning on the projection and rendering to a slightly larger surface to avoid some clipping.
