Proxies: a composition proxy draws with Separate Fields, Invert Alpha, linear light and Frame Blending

Browse Source 
For a precomp layer whose composition had a proxy, the renderer
decoded the proxy file with frame_with and drew it as decoded.
Interpret Footage > Proxy's Invert Alpha, Interpret As Linear Light
and Separate Fields had no effect on the render, and neither did the
layer's Frame Blending. A footage item's proxy already goes through
footage_frame and gets all of them.

The composition proxy now goes through footage_frame too, so it is
decoded the way a footage proxy is.
