"DRAWINDEX number
Defines the drawing order of 2D Script elements. Elements with a smaller drawindex will be drawn first.
Restriction of parameters: 0 < number <= 50 (In the current version of GDL only the 10, 20, 30, 40 and 50 DRAWINDEX values are valid. Other values will be rounded to these.)
If no DRAWINDEX directive is present, the default drawing order is the following:
1) Figures
2) Fills
3) Lines
4) Text elements"
For the default drawing order, the higher numbers are in front. (Lines on top of fills.) Within each element type, elements later in the script are in front.
