Description Pratik Solanki 2014-02-05 10:10:08 PST 
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().

Retracting patch. This needs to be fixed in a better way than having a flag on TileCache.
