Yes, this is not the problem forbid to the user to change the render,
but a problem that it should vary (we we use different DLL for OpenGL
and Direct3D). The basic essence of a problem that we want to check
that did not remain references to objects and functions (!) from this
DLL. The idealest variant would be such at which these references
received value nil. How it is possible to make this?
