Excellent, this is the type of thing I'm hoping the SceneGraphTestBed
will be able to host, it's why I created the repo on github.  I've
thinking of a small test framework, tests and supporting data.  If you
can create something to illustrate what it could look like this would
be really useful.  This work can happen independently from the
VulkanSceneGraph work, once the later is usable/testable we can then
start adding VulkanSceneGrpah specific support.  Until the
VulkanSceneGraph is ready the test framework could build upon the
OpenSceneGraph.

Setting a C++11 as base for SceneGraphTestBed would be fine. This is a
big topic for discussion so probably best to create a separate thread
for it.

The issue is that there are just sooooo many plugins it's a blessing and a curse. A system which when I generated my project let me select the plugins I wanted would be awesome. A full build of osg on mobile platforms can take well over an hour but it's mainly the plugins users will probably never use that take all the time.

Perhaps additions to CMake might help.   Essentially you'd want to be
able to define white list of what you are happy building, not sure how
easy this would be to implement.  I'm open to suggestions, but for
changes to the OSG we need a separate thread.

Cheers,
Robert.
