John Bowler	dc63b03da1	[libpng17] Completed full working pngimage test program and added two test scripts. Fixed combination of ~alpha with shift. On read invert alpha, processing occurred after shift processing, which causes the final values to be outside the range that should be produced by the shift. Reversing the order on read makes the two transforms work together correctly and mirrors the order used on write.	2014-02-05 11:39:59 -06:00
