Brian Salomon dd4087d1e8 GrSurfaceContext::read/writePixels takes GrPixmap
Change readPixels contract to allow unknown->unknown AT reads, but
fail if one side is unknown and the other isn't (and update GPU read
pixels test accordingly).

Also, ProxyUtils::MakeTextureProxyViewFromData takes GrPixmap.
