Allow to set lower RTTs resolution.

Browse Source 
It allows to increase performance on devices that have only one available resolution.

It also allows to draw GUI elements in full resolution while rendering the scene with slightly lower resolution, which gives you few additional FPS.

Note that particles don't work as expected yet with this feature.
