From: Søren Sandmann Pedersen <s...@redhat.com>
In fast_composite_tiled_repeat() if the source image is less than a
certain constant width, a clone is created which is then
pre-repeated. However, the source image's palette, if it has one, is
not cloned, so for indexed images, the pre-repeating would crash.
Fix this by not doing any pre-repeating for images with a palette set.
