 * ICON (DVASPECT_ICON) METAFILE FORMAT:
 *
 * The metafile generated with OleUIMetafilePictFromIconAndLabel contains
 * the following records which are used by the functions in DRAWICON.C
 * to draw the icon with and without the label and to extract the icon,
 * label, and icon source/index.
 *
 *  SetWindowOrg
 *  SetWindowExt
 *  DrawIcon:
 *      Inserts records of DIBBITBLT or DIBSTRETCHBLT, once for the
 *      AND mask, one for the image bits.
 *  Escape with the comment "IconOnly"
 *      This indicates where to stop record enumeration to draw only
 *      the icon.
 *  SetTextColor
 *  SetTextAlign
 *  SetBkColor
 *  CreateFont
 *  SelectObject on the font.
 *  ExtTextOut
 *      One or more ExtTextOuts occur if the label is wrapped.  The
 *      text in these records is used to extract the label.
 *  SelectObject on the old font.
 *  DeleteObject on the font.
 *  Escape with a comment that contains the path to the icon source.
 *  Escape with a comment that is the ASCII of the icon index.

/*
 * OleStdIconLabelTextOut
 *
 * Purpose:
 *  Replacement for DrawText to be used in the "Display as Icon" metafile.
 *  Uses ExtTextOut to output a string center on (at most) two lines.
 *  Uses a very simple word wrap algorithm to split the lines.
 *
 * Parameters:  (same as for ExtTextOut, except for hFont)
 *  hDC           device context to draw into; if this is NULL, then we don't
 *                ETO the text, we just return the index of the beginning
 *                of the second line
 *  hFont         font to use
 *  nXStart       x-coordinate of starting position
 *  nYStart       y-coordinate of starting position
 *  fuOptions     rectangle type
 *  lpRect        rect far * containing rectangle to draw text in.
 *  lpszString    string to draw
 *  cchString     length of string (truncated if over OLEUI_CCHLABELMAX)
 *  lpDX          spacing between character cells
 *
 * Return Value:
 *  UINT          Index of beginning of last line (0 if there's only one
 *                line of text).
 *
