Reviewed by Tim Nguyen.

Before this commit, those properties didn't have their own
initialization function and default-initialized to Color {},
which is an invalid color and thus is later "interpreted" as
currentcolor, correctly having an "implicit" current color behavior.
This commit makes this behavior explicit, and will allow changing the
underlying representation of "current color" in the future.
