The Zooming tiling mode in TileCache is not always accurate. UIKit sets it to Zooming even in cases when it does a pan instead of a zoom. In such situations we can end up with blurry tiles created with 0.125 scale factor. See RenderLayerCompositor::contentsScaleMultiplierForNewTiles().

Comment on attachment 223247 [details] Patch Retracting patch. This needs to be fixed in a better way than having a flag on TileCache.
