Remove darker composite operator (removed)

deprecate darker composite operator because Compositing spec [1] doesn't contain "darker" composite operator. [1] http://dev.w3.org/fxtf/compositing-1

Comments

Motivation 1. Compositing spec doesn't contain "darker" composite operator. 2. "darker" is a quirk that is exclusive to WebKit. 3. "darker" composite operator is implemented in the same way to "darken" blend mode. So web developers can use "darken" instead of "darker".
