Fixed test failures when gnuplot is not installed:

There was no particular reason to be using gnuplot for the tests in findobj.m. As I noted in comment #2, there are lots of BIST tests that were using gnuplot solely to have access to invisible figures which is unnecessary. I fixed that here (http://hg.savannah.gnu.org/hgweb/octave/rev/ba4088aee342).

I changed the bug summary to refer only to copyobj.

Just a minor update, the tests now simply fail instead of hanging, with an error "graphics_toolkit: gnuplot toolkit is not available".

When _osmesa_print_ is finally completely debugged, then printing of invisible figures from OpenGL will work and this bug can be closed.

It would be better, perhaps, to search through the built-in tests and identify those which are using gnuplot solely because it supported invisible figures in the past and remove that requirement.

This is the same OpenGL printing bug which keeps popping up. The test for copyobj () creates an image and saves it to a file. But this this can't happen if the figure visibility is set to 'off' as it is for all of the built-in tests to prevent random graphs popping up on screen.

I'm marking this bug as postponed until the underlying OpenGL issue is fixed.

when gnuplot, the test from copyobj kinda of fails. It makes Octave hang after warning and errors:
