The requested width and height of the image part of the label
is taken from the width and height of the image.

Longer answer: the "label" element is a combination of the
"text" and "image" elements, with additional options "-compound",
"-anchor", and "-space" that specify how the two parts
should be arranged.

For "-compound top" and "-compound bottom", the requested
height is the height of the image, plus "-space", plus the
height of the text element, and the requested width is the
maximum of the widths of the two subelements.  Similarly for
"-compound left" and "-compound right", except width and
height are swapped.  For "-compound text" and "-compound image",
only the appropriate subelement is used.

If -width >= 0, the requested width of the text element
is -width characters.  Otherwise, it's the the larger of
the width of the string and the absolute value of -width
(i.e., negative -widths specify a minimum size for the
text element).
