is.small(x)
A unit.
Logical or NA
.
Based on arbitraily chosen definitions of 'small', this function can return
TRUE
or FALSE
if a unit is 'small'.

'small'.
Unresolved sizes, suchs as 'grobheight', 'grobwidth', or 'null' are not
small.
Units based on arithmetic, such as sum of multiple units,
are also not small.
NA
s are returned for undecided sizes.
