73e28ef13d [devel] Reverted changes to call png_longjmp in contrib/gregbook 
where it is not appropriate.  If mainprog->jmpbuf is used by setjmp,
then png_longjmp cannot be used.
Reversed patch to remove error handler when the jmp_buf is stored in the
main program structure, not the png_struct.
The error handler is needed because the default handler in libpng will
always use the jmp_buf in the library control structure; this is never
set.  The gregbook code is a useful example because, even though it
uses setjmp/longjmp, it shows how error handling can be implemented
using control mechanisms not directly supported by libpng.  The
technique will work correctly with mechanisms such as Microsoft
Structure Exceptions or C++ exceptions (compiler willing - note that gcc
does not by default support interworking of C and C++ error handling.)

82980f31d9 [devel] Make png_set_sRGB_gAMA_and_cHRM set values using either the fixed or 
floating point APIs, but not both.

a272d8fe3d [devel] Made FIXED and FLOATING options consistent in the APIs they enable 
and disable.  Corrected scripts/options.awk to handle both command line
options and options specified in the .dfa files.

4a4de1899a [devel] Added logunsupported=1 to cause pnglibconf.h to document disabled 
options.  This makes the installed pnglibconf.h more readable but causes no
other change.  The intention is that users of libpng will find it
easier to understand if an API they need is missing.

cf2fd3b6ca [devel] Corrected protection of png_get_user_transform_ptr.

are turned off but was left defined in pngtrans.c

5905484c75 [devel] Corrected PNG_REMOVED macro to take five arguments. 
The macro was documented with two arguments (name,ordinal), however
    the symbol checking .dfn files assumed five arguments.  The five
    argument form seems more useful so it is changed to that.

9ee577c7f5 [devel] Changed Windows calling convention back to __cdecl for API functions. 
For Windows/x86 platforms only:
  __stdcall is no longer needed for Visual Basic, so libpng-1.5.0 uses
  __cdecl throughout (both API functions and callbacks) on Windows/x86
  platforms.

c3d73f4da9 [devel] Added PNG_{READ,WRITE}_INT_FUNCTIONS_SUPPORTED. 
This allows the functions
to read and write ints to be disabled independently of PNG_USE_READ_MACROS,
which allows libpng to be built with the functions even though the default
is to use the macros - this allows applications to choose at app build
time whether or not to use macros (previously impossible because the
functions weren't in the default build.)

8bdfb47d8c [devel] Moved replacements for png_error() and png_warning() from the 
contrib/pngminim project to pngerror.c, for use when warnings or
    errors are disabled via PNG_NO_WARN or PNG_NO_ERROR_TEXT, to avoid
    storing unneeded error/warning text.
