Tomato Cycles: fix for wrong resolution used for rendering Render Layer node

Issue was caused by Cycles using render options from rendering scene, not
from active scene.

For now solved by passing render resolution inside RenderEngine structure.
This probably could be solved in more general way, like adding bindings

for RenderEngine->Render, which would avoid passing options like
is_animation, came_override and so via RenderEngine. Would think about
this a bit more and probably would do that.

The same issue happens in trunk as well, but not consider such a change
trunk-ready, would want to make more tests and probably clean the code
a little bit before commiting this into trunk.
