Mmm... well it looks like NSTableColumn's -width might is returning
the same size that I actually get asked to draw in my NSCell subclass,
so perhaps this is indeed simple/quick.
I was concerned that intercell spacing, grid etc. might have to come
out of the column width before the cell width residual is known - but
if the column width is always the same as the drawable cell width then
that's great.

I can get the 'prototypical' cell object by asking for the pertinent
NSTableView column, and then asking for the cell. I can see that
NSCell supports a range of methods under the heading "Determining
Cell Size" in the docs.
The method -drawingRectForBounds: looks promising, but it takes
another rectangle, i.e. the "bounds". Assuming that this method
would give me what I want, how do I first obtain the appropriate
'bounds' to feed it?
Perhaps this method is only intended to provide information to the
system by the NSCell implementation and is not intended for the
purpose I need. In which case, is there a way to achieve what I
want without having to ask for the NSTableColumn width and working
out what proportion of this width is used for non-'interior'
furniture (if any)?
