Displays the Add Bitmaps dialog box, and gets the options for L_AddBitmaps.

Parameter	Description
hWndOwner	Handle of the window which owns the dialog.
pDlgParams	Pointer to a ADDBITMAPSDLGPARAMS structure to be updated with the values entered by the user, through the dialog. Set members of this structure, before calling this function, to set the dialog’s initial values.
