John Bowler	c2a8a01b2a	makepng --small ... This patch adds code to 'makepng' to allow the generation of smaller images that also give better test case coverage. It also adds copyright and licence to the generated images, reflecting the fact that they are original works of the author of the code. The licence used is the Creative Commons Public Domain one, appropriate to a non-source-code work. The resultant image were used to generate the updated pngstest-errors.h file in a prior commit.

John Bowler	8a9a3fb4dd	pngstest: make error limits version specific ... Splitting the machine generated error structs out to a file allows the values to be updated without changing pngstest.c itself, sine libpng 1.6 and 1.7 have slightly different error limits this simplifies maintenance. makepngs.sh has also been updated to more accurately reflect current problems in libpng 1.7 Signed-off-by: John Bowler <jbowler@acm.org>	2015-09-19 16:21:36 -07:00
