the rectangle that bounds the icon, the expanded and collapsed icon or bit
map, and the text.
CMA_ICON
Returns the icon rectangle.
CMA_TEXT
Returns the text rectangle.
CMA_TREEICON
Returns the rectangle of the
expanded and collapsed icons or bit maps. This flag is valid for the tree
icon and tree text views only.
