    This tests verifies that filters work even on composited layers that fallback to rendering in software.
    NOTE: It is using the fact that Safari can draw drop-shadows in GPU only if the filter is the last one in the filter chain.
    You should see three green rectangles slightly rotated and blurred. There should be no red.
