Multisprite DGRP display

The default DGRP display on the IFFSnooper tab panel is one sprite at a time. Nevertheless it may be useful to see all available sprites at once. The View -- DGRP resource submenu selections modify how the DGRP sprites are displayed, as shown below.

Filtered drawgroup
This shows the DGRP resource after selecting a different set of sprites. The image of a single snowman in game is achieved by the use of SimAntics code to control the dynamic sprites.
