Prevent setting or writing over-length PLTE chunk (Cosmin Truta).
Silently truncate over-length PLTE chunk while reading.
+ Libpng incorrectly calculated the output rowbytes when the application
+ decreased either the number of channels or the bit depth (or both) in
+ a user transform. This was safe; libpng overallocated buffer space
+ (potentially by quite a lot; up to 4 times the amount required) but,
+ from 1.5.4 on, resulted in a png_error (John Bowler).
