c5bef946b1 [devel] IDAT compression failed if preceded by a compressed text chunk
This was because the attempt to reset the zlib stream in png_write_IDAT
happened after the first IDAT chunk had been deflated - much too late.
In this change internal functions are added to claim/release the z_stream
and, hopefully, make the code more robust.  Also deflateEnd checking is
added - previously libpng would ignore an error at the end of the stream.

b3edc73afa [devel] Changes to remove gcc warnings (John Bowler)
Certain optional gcc warning flags resulted in warnings in libpng code.
With these changes only -Wconversion and -Wcast-qual cannot be turned on.
Changes are trivial rearrangements of code.  -Wconversion is not possible
for pngrutil.c (because of the widespread use of += et al on variables
smaller than (int) or (unsigned int)) and -Wcast-qual is not possible
with pngwio.c and pngwutil.c because the 'write' callback and zlib
compression both fail to declare their input buffers with 'const'.

Also corrected zlib.vcxproj into which Visual Studio had introduced

simply copies the file; in the future it may actually generate the
file from scripts/pnglibconf.dfa as the other build systems do.

e600c51355 [devel]Made all API functions that have const arguments and constant string
literal pointers declare them (John Bowler).
Many APIs did not change their arguments but were not declared using
PNG_CONST.  This change corrects this.  In a few cases APIs that return
constant string literal pointers have also been changed to declare this.
Unlike the argument change this may require app changes; however the
results could never be written to (the app would crash on some platforms
where strings are not writable), so this seems advisable.

77396b63f9 [devel] VisualC/GCC warning fixes, VisualC build fixes
The changes include support for function attributes in VC in addition to
    those already present in GCC - necessary because without these some
    warnings are unavoidable.  Fixes include signed/unsigned fixes in
    pngvalid and checks with gcc -Wall -Wextra -Wunused.
  VC requires function attributes on function definitions as well as
    declarations, PNG_FUNCTION has been added to enable this and the
    relevant function definitions changed.

31aee0d0c0 [devel]
Fixed point APIs are now supported throughout (no missing APIs).
  Internal fixed point arithmetic support exists for all internal floating
    point operations.
  sCAL validates the floating point strings it is passed.
  Safe, albeit rudimentary, Watcom support is provided by PNG_API_RULE==2
  Two new APIs exist to get the number of passes without turning on the
    PNG_INTERLACE transform and to get the number of rows in the current
    pass.
  A new test program, pngvalid.c, validates the gamma code.
  Errors in the 16 bit gamma correction (overflows) have been corrected.
  cHRM chunk testing is done consistently (previously the floating point
    API bypassed it, because the test really didn't work on FP, now the test
    is performed on the actual values to be stored in the PNG file so it
    works in the FP case too.)
  Most floating point APIs now simply call the fixed point APIs after
    converting the values to the fixed point form used in the PNG file.
  The standard headers no longer include zlib.h, which is currently only
    required for pngstruct.h and can therefore be internal.

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.

is defined.  We are considering removing it entirely.

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.

34713ce23c [devel] Fixed dependencies of GET_INT_32 - it doesn't require READ_INT_FUNCTIONS
because it has a macro equivalent.
