Log:
	Benjamin Otte (4):
	      Make the text when reporting a broken region more useful

	      Explain how we can simplify the radial gradient computation
	
	Siarhei Siamashka (3):
	      Test program for stressing the use of different formats and operators
	      HACK: updated test to better cover new neon optimizations
	      One more update to blitters-test - use aligned memory
	
	Søren Sandmann Pedersen (56):
	      Post-release version bump
