R3xx/R4xx: Maximize the use of clipped triangles for Xv rendering
While trying to get tear free video on my RS690 I found some problems in the code for rendering the video as a clipped triangle. The size limitations are quite strict and scaling the video output window creates all kinds of weird effects. This patch maximizes the use of this function and resolves the scaling issues. There could be a problem with zero target height/width, not sure if this is handled elsewhere.
