 Priority:  major       |   Milestone:  2.11 Release

------------------------+---------------------------------------------------
 r10755 brings a regression, because the code shuffling needed for making
 Tile.Image.IFrame a mixin caused an unintended change in execution flow:
 renderTile needs to update the viewRequestID every time, and not just when
 a new imgDiv is created.

 The way Tile.Image.IFrame is mixed in will cause the mixin to always be
 applied, unless the maxGetUrlLength is explicitly set.

 The attached patch fixes these regressions. All tests pass. Thanks for any
 review
