I see, I did not realize such simple usage of \clip (without options).
That do exactly what was thinking about. One character of typing
difference between:
\clip{\externalfigure{test}}
and
\externalfigure[clip]{test}
is not crutial:) So sorry for noise.
But as far as I know, \clip works only with left|top,width|height
params. Could right|bottom be added (assuming at least one from
left-width-right and top-height-bottom is missing - if not width|height
is ignored)? Or there is again some secret that I missed?
