added 'drawn' property to all tiles. removed redraw() and adapted all draw()s to auto handle redraw. remove getPosition() accessor that noone was using. set generic Tile's moveTo() to auto trigger the clear() and the redraw() (if desired). Update Image and WFS tile classes correspondingly. also update tests
