Drawing Modes
In the Drawing Mode section you can choose from the following
Drawing Modes. If any of the options in this section are grayed out, then
they are not available for the model controller with which you are
working.
Enable DirectDraw: This option allows the user to enable or disable
DirectDraw. DirectDraw is a software interface that provides direct
