libpng-1.4.4

[thomas]

libpgn could be updated to 1.4.4. I went thru LFS/BLFS to X (7.6-RC1 btw) and the only issue was at Xulrunner. The apng-patch is available at ​http://littlesvr.ca/apng/diff/libpng-1.4.4-apng.patch, and at XulRunner i need to add

Everything else went fine.

I've been using 1.4.4 on an lfs-svn-20101029 platform for a long time now, and have not had any issues. I did not have any problems (no seds or patches) installing Xulrunner-1.9.2.13.

There is now a version of libpng, 1.5.0. There must be some reason to change the minor version from 1.4.x to 1.5.x. I have not looked at ChangeLog or anything.

I'll probably update BLFS to 1.4.4 for the release, and we can update to 1.5.x after. If anyone has other suggestions, bring 'em on.

Well, it does hide structure members from public view (probably for encapuslation). I found this out when I was building TeXLive with libpng 1.5.1.

For the curious, the patch to fix the TeXLive issues is here:

Also of note, the manual file is now called libpng-manual.txt, not libpng-<version>.txt.

Additionally, the 1.5.0 tree started with this commit on Feb. 7, 2010 (a little more than a year ago):

Moved declaration of png_struct into private pngstruct.h and png_info
    into pnginfo.h
