Bug#747211: scilab: Allow scilab gui to start without opengl

Package: scilab
Version: 5.5.0-2
Severity: wishlist

Dear Maintainer,

Currently under testing, using virtualbox there are some problems with the vboxvideo driver, and thus full opengl support is difficult to access (software rendering only). This happens quite frequently on many systems, for various reasons.  The module is installed, but cannot be used.

https://www.virtualbox.org/ticket/12746

Thus it would be nice if scilab could start, and use opengl when only software rendering is available. I realise that this may be a complex reuquest, as this I am sure reaches deep into gluegen/jogl initialisation.

For anyone searching, the following errors occur when launching scilab (scilab-bin, inside the do_scilex function). glxgears runs, but only with low framerates. 

libGL error: pci id for fd 4: 80ee:beef, driver (null)
OpenGL Warning: Failed to connect to host. Make sure 3D acceleration is enabled for this VM.
libGL error: core dri or dri2 extension not found
libGL error: failed to load driver: vboxvideo

I've attached a slightly redacted strace log.

Thanks!
