Okay, how's this for an alternative... leave the current behavior as it is,
with the addition of a new value for alt_maxwidth/alt_maxheight of "noalts"
or of "-1" or of "none".
My fear is that changing current behavior is nearly always bad to
someone. But this would allow the user to override the default behavior at
the specific level by using values that are not currently in-use and have
no current expected behavior. And it's still a smallish, simple addition.
