Robert Bragg f2f4f5f06f [cogl journal] Perform software modelview transform on logged quads.
Since most Clutter actors aren't much more than textured quads; flushing the
journal typically involves lots of 'change modelview; draw quad' sequences.

The amount of overhead involved in uploading a new modelview and queuing
that primitive is huge in comparison to simply transforming 4 vertices by
the current modelview when logging quads.  (Note if your GPU supports HW
vertex transform, then it still does the projective and viewport transforms)

At the same time a --cogl-debug=disable-software-transform option has been
added for comparison and debugging.

This change allows typical pick scenes to be batched into a single draw call
and I'm seeing test-pick run over 200% faster with this.  (i965 + Mesa
7.6-devel)
