There's one other alternative: extend display_string to accept
FIELD_WIDTH in pixel units (or add another argument to that effect).
This could be set by examining the 'display' property before calling
display_string.  The disadvantage is that only the min-width spec
could be supported this way for mode-line constructs that are produced
from C strings.
