@Andreas: Do you want to bring up the question of making OSMesa experimental on the OCtave-Maintainer's mailing list? It would be simplest for this release to make it experimental.

There is in configure.ac:

We had a quick discussion on the mailinglist that the configure script doesn't check for versions but rather for bugs or functions. The problem here is, that OSMesa only fails if linked with Octave. (a typical bootstrap problem).

On my tests with OSMesa on Debian I figured out that one symptom from linking Octave against an old libosmesa is, that the buffer_depths are totally screwed up when reading back and I used this to show an hint.

We have alo bug #44478 which makes OSMesa completely useless if proprietary Nvidia drivers are used.

Perhaps we should mark OSMesa as experimental and disable it per default.

Testing octave 4.0.0-rc4 on CentOS 5.11. Tests for osmesa_print fail correctly because of old version being used.

Indeed Octave was built with version OSMesa 6.5.1 but if we know this, shouldn't this test be done by configure instead?
