History
Chris Wilson 97efbd25fe Use CLAMP_TO_BORDER in copy_n_to_n so we can sample outside of the source 
In order to reduce a composite operation to a source, we need to provide
Render semantics for the pixel values of samples outside of the source
pixmap, i.e. they need to be rgba(0, 0, 0, 0). This is provided by using
the CLAMP_TO_BORDER repeat mode, but only if the texture has an alpha
channel.
