Add new filter repaint test for turbulence, rebaseline existing test

This patch adds a new (currently failing) filter repaint test to show how we improperly repaint turbulence filters. In addition, the existing test for 640264 has been unskipped and rebaselined with a failing result. These two changes should help catch progressions in the future.
