[_drawOrder] Section
At a minimum, your input file must define the draw order for ALL polygon types – not just
your custom ones. Even if you don’t define any custom polygon types in your source file,
this section is mandatory. If a polygon type is not defined in the [_drawOrder] section,
it will not be rendered on your GPSr. If a polygon type is not showing up, check to make
sure that it is listed in your [_drawOrder] section, and that it has a higher priority
number than any other overlapping polygons.
Each statement in the [_drawOrder] section includes the hex ID of the defined polygon
type and its relative draw order. Higher numbers are rendered later. Therefore, a polygon
defined with a priority of 1 will be drawn first, and overwritten by an overlapping polygon
defined with a higher number (2-8). Priority numbers are between 1 and 8. For example,
in the [_drawOrder] section below, a Shopping center (Type 8, priority 3) will be shown on
top of a large urban area (Type 0x01, priority 1).
