------- Additional Comments from Mihai Tica <mitica at adobe.com>
Adding tests to check if isolation is performed. Besides testing each blend
mode, this patch also validates that opacity, webkit-shadow, masks, filters and
blending cause isolation. As the spec states, clip-path doesn't isolate. Note
that while masking doesn't create a transparency layer, the contents of the
masked element are drawn in a separate buffer, thus creating isolation.
