Bas Schouten fdee1bb880 Bug 1083245: Pop all clips before copying to the destination blending surface. r=jrmuizel 
We need to pop the clips from the decide context before flushing and copying to the destination blending surface, otherwise drawing commands executed on a pushed layer for clipping will not be realized on the destination surface for blending.

Note that this fixes most situation, but in the case of doing custom blending to an area of a surface which is not opaque while having a complex clip pushed this will still lead to some artifacts. I haven't seen this be a problem in practice though.
