You wouldn't want to scale a single pixbuf like that.  It would probably
be slower, not faster, after you upload the pixel data into a texture
and then do a readback of the buffer.

If you upload the pixel data and apply it as a texture to a surface and
scale that surface many times without doing any readbacks, that would be
fast.  But that's a different situation from doing a general-purpose
scale of a pixbuf.
