Limits the range of possible values which can be entered in field # field of the
SizeEntry.
The current value of the field will be clamped to fit in the field's new boundaries.
NOTE: In most cases you won't be interested in this function because the SizeEntry's purpose is to shield the programmer from unit calculations. Use set_refval_boundaries instead. Whatever you do, don't mix these calls. A size entry should either be clamped by the value or the reference value.
