------- Additional Comments from Bruce Q. Hammond <bruceq at apple.com>
This fixes style guidelines conformance.

Changes technique to detect CGBitmapContext to be less fragile and one that we
hope will be sanctioned in future OS X releases.

Also removes trailing whitespace from lines.

This has been tested for regressions in Safari.
No unit tests seems to be practical.
