/*++

Routine Description:

    This routine draws a status area item into a given dc.  This
    includes drawing the nice shaded button-like container, and
    then drawing text within it.

Arguments:

    rc      - rectangle describing the status area item

    hdc     - device context into which to draw

    Text    - optional parameter that if present represents text to
              be placed in the item.

    Unicode - if TRUE, Text points to a wide character string regardless
              of the type of LPTSTR

Return Value:

    None.
