------- Additional Comments from Mahesh Kumar <mahesh4gnu at gmail.com>
https://bugs.webkit.org/show_bug.cgi?id=39027 added
CanvasRenderingContext2D::shouldDisplayTransparencyElsewhere() &
CanvasRenderingContext2D::displayTransparencyElsewhere() to draw transparency
for the remaining canvas area for CompositeSourceIn & CompositeSourceOut.

I have also added to check for CompositeDestinationAtop to draw transparency in
remaining canvas area before Image draw for destination-atop compositing.
