Integer property with the

the Up (not pressed) state. ExternalImageIndex is an indexed property which
accesses the value stored in an internal array of image indexes for each of
the button states. The property value contains the ordinal position in
ExternalImages with the bitmap used for the button state. -1 indicates that
an explicit value has not been assigned for the property.
