89edbf8317 [libpng16] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the 
compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.

Glenn Randers-Pehrson
1088f4925f [libpng16] Fixed old cut&paste bug in the weighted filter selection code in

8ee821e69a [libpng16] PNG_RELEASE_BUILD replaces tests where the code depended on the build base 
type and can be defined on the command line, allowing testing in beta builds. Back
ported from libpng17.

0f12df19a1 [libpng16] Added PNG generation tool, fixed unitialized pointer in 
simpleover. Also added a comment to png.h pointing out that the pointer must
 be set to NULL!  (simpleover crashes with any slightly complex command lines
 without this fix.)

6eecfe3886 [libpng16] Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha 
value was wrong.  It's not clear if this affected the final stored
value; in the obvious code path the upper and lower 8-bits of the
alpha value were identical and the alpha was truncated to 8-bits
rather than dividing by 257 (John Bowler).

4b65a89cf4 [libpng16] Eliminated PNG_SAFE_LIMITS macro and restored the 1-million-column 
and 1-million-row default limits in pnglibconf.dfa, that can be reset
by the user at build time or run time.  This provides a more robust
defense against DOS and as-yet undiscovered overflows.

Display user limits in the output from pngtest.
