-/* A decent hack: reverse the effective order of the dropmarker and icon in RTL
-   mode so that the above CSS, which places the menubutton-start.png background
-   on the toolbarbutton-icon, will make sense. (Otherwise the dropmarker appears
-   outside the button.) Then just flip the entire thing horizontally! We want to
-   do that anyway so that the Locate button will point to the left and Sync will
-   rotate counter-clockwise.
-
-   The other way to do this would be to set direction: ltr on buttons in the
-   RTL toolbar, but that breaks popup positioning. */
