Routine Description:
This function return a WORD index of Imagelist which the icon should be
used in the treeview
Arguments:
pTVWnd - Our instance handle
hInst - The instance handle for the IconResID
IconResID - Caller's IconResID, it the high word is not zero then it
it assume it is a Icon handle, and if high word is 0xffff
then it assume the low word is the icon handle
IntIconID - compstui Internal icon ID to be used if the IconResID is
not available
Return Value:
WORD, index to the image list, 0xFFFF if failed

Fix bug that we will first only search the IconResID and if not found
then we try to find the IntIconID
