Subject: [PATCH] Bug 702320: Valgrind complains about UMR.

The file for this bug does show that the stroke_color stack based struct
in not initialized. Init fill_color and stroke_color. This is probably a
bug tail from the fill_stroke commit.

Also explicitly set 'zeros' to 0 to clarify the expected contents.
