        The previous code was assuming that we'll be painting buttons on the scrollbar
        which isn't true on Linux. To reproduce, resize a page with scrollbars until
        they are less than two widths high.

        This will need pixel test baselines to be updated in the Chromium tree.

        * platform/chromium/ScrollbarThemeChromium.cpp: move this function...
        * platform/chromium/ScrollbarThemeChromiumWin.cpp:
        (WebCore::ScrollbarThemeChromium::trackRect): ... to here
        * platform/chromium/ScrollbarThemeChromiumLinux.cpp:
        (WebCore::ScrollbarThemeChromium::trackRect): add an alternative which
        doesn't remove the track when the scrollbar is less than two widths
        high.
