Fixed performance issue with matplotlib in DebugVariablePanel and hide 3D graphics when not needed
/*
* DEBUGGER code
*
* On "publish", when buffer is free, debugger stores arbitrary variables
* content into, and mark this buffer as filled
*
*
* Buffer content is read asynchronously, (from non real time part),
* and then buffer marked free again.
