From 803083e51a378fe7069aaaae0092a0d516877281 Mon Sep 17 00:00:00 2001 From: stephena Date: Thu, 27 Sep 2012 22:17:27 +0000 Subject: [PATCH] Removed some debugging info from RIOT class. Updated PNG library to latest release. I hope to get back to Stella development soon, and do a new release in perhaps the next month or so. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2554 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba --- Changes.txt | 2 + src/emucore/M6532.cxx | 3 +- src/libpng/png.c | 18 ++++---- src/libpng/png.h | 94 +++++++++++++++++++++++------------------- src/libpng/pngconf.h | 38 +++++++++-------- src/libpng/pngerror.c | 2 +- src/libpng/pngmem.c | 8 ++-- src/libpng/pngpread.c | 5 ++- src/libpng/pngpriv.h | 8 ++-- src/libpng/pngrtran.c | 76 ++++++++++++++++++++++------------ src/libpng/pngrutil.c | 2 +- src/libpng/pngset.c | 10 +++-- src/libpng/pngstruct.h | 5 ++- src/libpng/pngtrans.c | 6 +-- src/libpng/pngwrite.c | 5 ++- src/libpng/pngwtran.c | 20 +++++++-- src/libpng/pngwutil.c | 3 +- 17 files changed, 177 insertions(+), 128 deletions(-) diff --git a/Changes.txt b/Changes.txt index 70c27806c..3b95dab75 100644 --- a/Changes.txt +++ b/Changes.txt @@ -28,6 +28,8 @@ everywhere.
