Rendering will now use a cached version of the mirrored source in order to reduce rendering cost drastically for heavy sources or scenes. Additionally rescaling now uses the internal scene instead of being a custom implementation, allowing for some new things. Rescaling now has a new option: Bounds Type! This option allows control over just how a source is scaled, by default it is set to Stretch, but there are other options that can keep the aspect ratio of the mirrored source in tact. Additionally the ScalingMethod struct has been replaced with obs_scale_type, which means that Bilinear Low Resolution is now no longer an option. Implements #35
