Remove the '--strict' in 1.6 because of the double-gamma-correction warning, update pngstest-errors.h for the errors detected with the new contrib/testspngs PNG test files. Signed-off-by: NJohn Bowler <jbowler@acm.org>

tests/pngstest-* are changed so that the new test files are divided into 8 groups by gamma and alpha channel. This makes each test take just under 5 seconds on a moderately up-to-date x86_64 system using libpng16 (test times are somewhat variable under libpng17 at present because of the lack of optimization in some gamma processing paths.) These tests have considerably better code and pixel-value coverage than contrib/pngsuite however coverage is still incomplete. Signed-off-by: NJohn Bowler <jbowler@acm.org>

functions. They unnecessarily duplicate png_set_filler() and png_set_add_alpha() which now work properly with 16-bit images.

input that was made in version 1.6.17beta01, to preserve legacy behavior even though it was incorrect. Instead, added new API png_set_filter_16() and png_set_add_alpha_16() that set a flag to make png_do_read_filter() interpret the filler bytes properly.

Splitting the machine generated error structs out to a file allows the values to be updated without changing pngstest.c itself, since libpng 1.6 and 1.7 have slightly different error limits this simplifies maintenance. Signed-off-by: NJohn Bowler <jbowler@acm.org>

This is a patch for libpng16. It incorporates fixes to the low-bit-depth gray background handling from libpng17 and turns one of the low-bit-depth gray cases that does work (and, indeed, did work before) in libpng16 Signed-off-by: NJohn Bowler <jbowler@acm.org>

This updates libpng16 with all the test changes from libpng17, including changes to pngvalid.c to ensure that the original, distributed, version of contrib/visupng/cexcept.h can be used. pngvalid contains the correction to the use of SAVE/STORE_ UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7. More tests contain the --strict option to detect warnings and the pngvalid-standard test has been corrected so that it does not turn on progresive-read (there is a separate test which does that.) Some signed/unsigned fixes have been made. Signed-off-by: NJohn Bowler <jbowler@acm.org>

replacing the value that is illegal in the PNG spec, in both signed and unsigned values, with 0. Illegal unsigned values (anything greater than or equal to 0x80000000) can still pass through, but since these are not illegal in ANSI-C (unlike 0x80000000 in the signed case) the checking that occurs later can catch them (John Bowler).

0x8000 flag definitions on 16-bit systems. They aren't supported yet the defs *probably* work, however it seems much safer to do this and be advised if anyone, contrary to advice, is building libpng 1.6 on a 16-bit system. It also adds back various switch default clauses for GCC; GCC errors out if they are not present (with an appropriately high level of warnings).
