There's the challenge : On small displays (cellphones), download maps
does not work, because the name of a long way is often rendered on a
tile that is too far from the current from the current location.
Formal SVG is too slow because it uses things like bezier curves and xml.
But primitives like lines, polygons, rotated text and bitblts (for
icons) are often implemented in assembly or hardware, so they should
be faster than decompressing pngs.
