[Pixman] [PATCH 1/3] affine-test: Print out the transformation matrix when verbose

From: Søren Sandmann Pedersen <ssp at redhat.com>

Printing out the translation and scale is a bit misleading because the
actual transformation matrix can be modified in various other ways.

Instead simply print the whole transformation matrix that is actually
used.
