It is better to use a more meaningful name. This can be a general macro that
will be useful outside of the figure inclusion code as well.
Ok. What about \scratch_current_width, \scratch_current_height,
\scratch_nocrap ? Or something similar...
Hans already added a generic function \setemeasure to syst-aux, that can
be used here.
Note that a simple \doifnotemptyvalue is not enough. I can pass values
like 'fit', 'max', etc to height and width keys, so you must check if what
is being passed is a dimension before calling \dimexpr.
