Subject: [PATCH] Bug 695890: Update jbig2dec for modern libpng
|
|
||||||
|
|
||||||
libpng 1.5.x and newer hide the internals, and only allow values to be set and
|
|
||||||
retrieved via define API calls.
|
|
||||||
|
|
||||||
Also tidy up a couple of (benign) compiler warnings.
|
|
||||||
|
|
||||||
No cluster diffs.
