Plus/Minus Bitmap

The plus/minus bitmap is an optional bitmap, which indicates the current expand status of an item. Three bitmaps can be defined, one for a (non-expandable) leaf item, one for an expanded parent item and one for a non-expanded parent item, all the same size. All items share the same three bitmaps and based on the expand status, the appropriate graphic is displayed. Individual items cannot override the bitmaps used.

The SetPlusMinus function defines the plus/minus bitmaps used for all items.
