Suppresing figure creation

[Juan Pablo Carbajal]

Hi,

I been surfing the manual and I can't find (probably lack of the right
keyword, not lack of content) help relating the suppression of figure
creation.
What I mean is the following: is there anyway to call a plot command
without generating a figure but still creating the graphic object and
the handle to it?

I need this cause several test blocks in geom2d (package OF geometry)
check the correctness of the draw* functions by checking the data on
the handle to the graphic object. However, we do not need the tests to
generate a figure and it would be nice to prevent the creation of the
figure. This is also causing some problem to the Debian packagers who
run tests in text terminal only and get the ASCII output.

Thanks
