  * This effect will draw a dotted line (defined as a dashed lined with round caps and no on
  * interval). The radius of the dots is given by the strokeWidth and the spacing by the DashInfo.
  * Both of the previous two parameters are in device space. This effect also requires the setting of
  * a vec2 vertex attribute for the the four corners of the bounding rect. This attribute is the
  * "dash position" of each vertex. In other words it is the vertex coords (in device space) if we
  * transform the line to be horizontal, with the start of line at the origin then shifted to the
  * right by half the off interval. The line then goes in the positive x direction.
