       Type: Variable
   Category: Dashboard
    Summary: Code modifications for the DrawDashboardLine line-drawing routine
    Context: See this variable in context in the source code
 References: This variable is used as follows:
             * DrawDashboardLine uses shortAxis


 When drawing a line, the short axis is only stepped along when the slope error
 adds up to a whole pixel, so this steps along the shorter axis of the line's
 vector. See the DrawDashboardLine routine for details.
