1. changes weren't refreshed for windows/linux-mesa vulkan. This
is due to a reordering of the shaders when the shader source
is replaced. We fix this by ensuring the ordering before
writing out the edit.
Fixes#7286
2. A condition was flipped in the SourceFormatter causing the
format feature to not work on linux
3. The material update status wasn't really propagated to the
front-end due to not updating the status counter.
