Get the viewport of a view, applied to this render target.
A window is active only on the current thread, if you want to make it
active on another thread you have to deactivate it on the previous thread
first if it was active. Only one window can be active on a thread at a
time, thus the window previously active (if any) automatically gets
deactivated.
