Michael Fabian Dirks f8b14bdb46 libobs: Ensure scene items don't have pre-multiplied alpha 
Scene items would incorrectly have pre-multiplied alpha when they were
scaled with different scale filtering, when they were cropped, or when
the item itself was a scene.  This happens because the scene renders the
items to a texture in those cases, and when they are rendered to a
texture the blend function would be the default srcalpha/invsrcalpha
blend function, which would cause alpha to become pre-multiplied in the
texture's result rather than straight alpha.

This changes the behavior to directly copy the color/alpha to the
texture using the one/zero blend function instead, which makes the
resulting texture straight alpha.  (Note that you do not want to turn
off the blend mode for the same result because certain sources can have
custom drawing that may rely on blending being available)
