- Changed frame buffer locking mechanism so that the only place where a lock is needed is when the software renderer wants to access the render buffer, which is precisely for the duration of the RenderView function.

No more locking insanity! :)
There are no locking counters or other saveguards here that would complicate the implementation because there's precisely two places where this buffer must be locked - the RenderView functions of the regular and poly SW renderer which cannot be called recursively.
