  * state:  => Review
  * version:  2.11 RC3 => 2.11


Comment:

 This patch does 4 things:
  * Make clear in the APIdocs that the wrapDateLine option makes sense on
 the base layer only, and only when the base layer's extent is the world
 extent.
  * When calculating the grid layout, shift the left bound to the right
 until it is within the world extent,
  * When setting the bounds of a tile, wrap them around the dateline to
 avoid tile bounds that exceed the world bounds
  * The Tile's shouldDraw method checks now against up to 3 different
 extents, depending on if or how the extent crosses the dateline.

 This means that layers that cross the dateline can no be used, and the
 according tiles will always be displayed when they are inside the
 viewport.
