// CTool:
// A CTool is a thin-window button which can be inserted in a CToolboxWnd.
// Note that the tool is "owned" by a separate window, which is notified
// directly when the tool is used (pushed, dragged, unpushed, etc.).  The
// CToolboxWnd sends TM_* messages to the owning window.
//
// The graphics are completely calculated from the single bitmap given to
// the tool upon creation.  The pushed, disabled and unpushed states are
// drawn from the bitmap, which should be a two-color image without any
// chiseling button effects in it.  The graphic is centered in the button.
//
// For buttons defined with the TS_DRAG style, a cursor ID may be specified
// for the can't-drop state.  If not specified, the generic slashed-O
// cursor is used.
