will wait for https://codereview.chromium.org/2952763002/ to land. Once this change lands it's easier to check that the search is active (and doing it before would require a rewrite afterward anyway)

Had to update the asset colours manually because the skiafy tool does not handle colours, apparently.

This involved adding two lines:

NEW_PATH,
PATH_COLOR_ARGB, (followed by the appropriate colours)

after each CLOSE statement in the icon file. One PATH_COLOR_ARGB statement was needed at the beginning as well for the first path. note that the alpha value (the first hexadecimal value) is 0xFF for all of them.

Working on finishing the tests and getting the change reviewed now.
