* drawable when this is required. This is very tricky as we need to reapply ALL opengl states for the new
* context, need torecreate shaders, textures and other resources.
*
* The context manager already takes care of the state problem and for the other tasks code from Reset
* can be used. These changes are way to risky during the 1.0 code freeze which is taking place right now.
* Likely a lot of other new bugs will be exposed. For that reason request a depth stencil surface all the
