Regarding the "Note" you made in the CL description, it's actually ok not to
pass in a size parameter here (so, what you have here is correct). You can
remove the note from the CL description.

(Side note: When calling CreateVectorIcon() and no size parameter is passed in,
then we try to pull the size information from the corresponding .icon file. In
ash/resources/vector_icons, check_circle.1x.icon specifies a size of 20, so we
do not need to pass it in.)
