After r133056 it no longer suffices to check use the existing usesTileCacheLayer method on Windows. The change resulted in 3 crashing tests: compositing/rotated-tiled-clamped compositing/rotated-tiled-preserve3d-clamped fast/events/tabindex-focus-blur-all We should add in platform specific method for Windows that returns false for this method. In addition, compositing/rotated-tiled-clamped compositing/rotated-tiled-preserve3d-clamped need to be removed from the Windows skip list and Windows specific results are needed since they were newly added tests with r133056.
