draw_pixel_workaround? (Imlib2::Image)

    /*
     * Are we using the buggy imlib_image_draw_pixel() work-around?
     *
     * Versions of Imlib2 up to and including 1.0.5 had a broken
     * imlib_image_draw_pixel() call. Imlib2-Ruby has a work-around, which
     * simulates drawing a pixel with a 1x1 rectangle.  This method allows
     * you to check whether the work-around behavior is enabled.
     *
     * Examples:
     *   puts 'work-around is enabled' if Imlib2::Image::draw_pixel_workaround?
     *   puts 'work-around is enabled' if Imlib2::Image::bypass_draw_pixel?
     *
