Custom Image Primitives
These commands are used to draw the individual
primitives that make up user-defined images. All
the available colors and fill patterns are listed here.
An image cannot have more than 16 different colors
in it. Trying to use more than 16 colors causes un-
expected results. The command description section
lists what parameters are needed by each primitive.
Most of the custom image primitives require you to
specify their color.
