544747 - Update libpng to version 1.4.1

Status: VERIFIED FIXED

(Core :: Graphics: ImageLib, defect)

Description

[Glenn Randers-Pehrson]

I expect to release libpng version 1.4.1 on or about February 18th.  It offers increased speed and reduced memory usage compared to the current embedded libpng versions.

did all tests, reftest and otherwise continue to pass after that try run?

Comment 4

[Glenn Randers-Pehrson]

Yes, I received 9 messages from the Tryserver, reporting success on all builds and unittests.

Comment 5

[Max Stepin]

All arrays are local now, right? There are still some leftovers:

#ifdef PNG_USE_LOCAL_ARRAYS
#endif


Also, this line at the end of pngrutil.c is not needed:

png_uint_32 row_bytes;

Now that 1.4.1 is checked in we should require the system library to be at version 1.4.1 as well.  This would allow some simplification of nsPNGDecoder.cpp.  I'm spinning off bug #551438 for that.
