Detailed Description

Interpolate from YUV bitmap to RGB.

Creates internal, outbound frame with reserved space for AVFrame data
AVThread writes a Frame with it's av_frame (AVFrame) instance activated, into this FrameFilter
When first frame arrives here, reserve SwsContext (SwScaleFrameFilter::sws_ctx)
If incoming frame's dimensions change, re-reserve sws_ctx
