-1.3.0 2012-07-18
-  removed non-standard malloc.h from kiss_fft.h
-
-  moved -lm to end of link line
-
-  checked various return values
-
-  converted python Numeric code to NumPy
- 
-  fixed test of int32_t on 64 bit OS
-
-  added padding in a couple of places to allow SIMD alignment of structs
-
-1.2.9 2010-05-27
-  threadsafe ( including OpenMP )
-
-  first edition of kissfft.hh the C++ template fft engine
- 
-1.2.8 
-  Changed memory.h to string.h -- apparently more standard
-  
-  Added openmp extensions.  This can have fairly linear speedups for larger FFT sizes.
-
-1.2.7 
-  Shrank the real-fft memory footprint. Thanks to Galen Seitz.
-
-1.2.6 (Nov 14, 2006) The "thanks to GenArts" release.
-  Added multi-dimensional real-optimized FFT, see tools/kiss_fftndr
-  Thanks go to GenArts, Inc. for sponsoring the development.
-
-1.2.5 (June 27, 2006) The "release for no good reason" release.
-   Changed some harmless code to make some compilers' warnings go away.
-   Added some more digits to pi -- why not.
-   Added kiss_fft_next_fast_size() function to help people decide how much to pad.
-   Changed multidimensional test from 8 dimensions to only 3 to avoid testing 
-   problems with fixed point (sorry Buckaroo Banzai).
-
-1.2.4 (Oct 27, 2005)   The "oops, inverse fixed point real fft was borked" release. 
-   Fixed scaling bug for inverse fixed point real fft -- also fixed test code that should've been failing.
-    Thanks to Jean-Marc Valin for bug report.
-
-   Use sys/types.h for more portable types than short,int,long => int16_t,int32_t,int64_t
-   If your system does not have these, you may need to define them -- but at least it breaks in a 
-   loud and easily fixable way -- unlike silently using the wrong size type.
-
-   Hopefully tools/psdpng.c is fixed -- thanks to Steve Kellog for pointing out the weirdness.
-
-1.2.3 (June 25, 2005)   The "you want to use WHAT as a sample" release.
-    Added ability to use 32 bit fixed point samples -- requires a 64 bit intermediate result, a la 'long long'
-
-    Added ability to do 4 FFTs in parallel by using SSE SIMD instructions. This is accomplished by
-    using the __m128 (vector of 4 floats) as kiss_fft_scalar.  Define USE_SIMD to use this.
-    
-    I know, I know ...  this is drifting a bit from the "kiss" principle, but the speed advantages 
-    make it worth it for some.  Also recent gcc makes it SOO easy to use vectors of 4 floats like a POD type.
-
-1.2.2 (May 6, 2005)   The Matthew release
-    Replaced fixed point division with multiply&shift.  Thanks to Jean-Marc Valin for 
-    discussions regarding.  Considerable speedup for fixed-point.
-
-    Corrected overflow protection in real fft routines  when using fixed point.
-    Finder's Credit goes to Robert Oschler of robodance for pointing me at the bug.
-    This also led to the CHECK_OVERFLOW_OP macro.
-
-1.2.1 (April 4, 2004) 
-    compiles cleanly with just about every -W warning flag under the sun
-
-    reorganized kiss_fft_state so it could be read-only/const. This may be useful for embedded systems
-    that are willing to predeclare twiddle factors, factorization.
-
-    Fixed C_MUL,S_MUL on 16-bit platforms.
-
-    tmpbuf will only be allocated if input & output buffers are same
-    scratchbuf will only be allocated for ffts that are not multiples of 2,3,5
- 
-    NOTE: The tmpbuf,scratchbuf changes may require synchronization code for multi-threaded apps.
-
-
-1.2 (Feb 23, 2004)
-    interface change -- cfg object is forward declaration of struct instead of void*
-    This maintains type saftey and lets the compiler warn/error about stupid mistakes.
-            (prompted by suggestion from Erik de Castro Lopo)
-
-    small speed improvements
-
-    added psdpng.c -- sample utility that will create png spectrum "waterfalls" from an input file
-        ( not terribly useful yet)
-
-1.1.1 (Feb 1, 2004 )
-    minor bug fix -- only affects odd rank, in-place, multi-dimensional FFTs
-
-1.1 : (Jan 30,2004)
-    split sample_code/ into test/ and tools/
-
-    Removed 2-D fft and added N-D fft (arbitrary)
-
-    modified fftutil.c to allow multi-d FFTs
-
-    Modified core fft routine to allow an input stride via kiss_fft_stride()
-    (eased support of multi-D ffts)
-
-    Added fast convolution filtering (FIR filtering using overlap-scrap method, with tail scrap)
-
-    Add kfc.[ch]: the KISS FFT Cache. It takes care of allocs for you ( suggested by Oscar Lesta ).
-
-1.0.1 (Dec 15, 2003)
-    fixed bug that occurred when nfft==1. Thanks to Steven Johnson.
-    
-1.0 : (Dec 14, 2003)
-    changed kiss_fft function from using a single buffer, to two buffers.
-    If the same buffer pointer is supplied for both in and out, kiss will
-    manage the buffer copies.
-
-    added kiss_fft2d and kiss_fftr as separate source files (declarations in kiss_fft.h )
-
-0.4 :(Nov 4,2003) optimized for radix 2,3,4,5
-
-0.3 :(Oct 28, 2003) woops, version 2 didn't actually factor out any radices other than 2.
-        Thanks to Steven Johnson for finding this one.
-
-0.2 :(Oct 27, 2003) added mixed radix, only radix 2,4 optimized versions
-
-0.1 :(May 19 2003)  initial release, radix 2 only

-KISS FFT - A mixed-radix Fast Fourier Transform based up on the principle, 
-"Keep It Simple, Stupid."
-
-    There are many great fft libraries already around.  Kiss FFT is not trying
-to be better than any of them.  It only attempts to be a reasonably efficient, 
-moderately useful FFT that can use fixed or floating data types and can be 
-incorporated into someone's C program in a few minutes with trivial licensing.
-
-USAGE:
-
-    The basic usage for 1-d complex FFT is:
-
-        #include "kiss_fft.h"
-
-        kiss_fft_cfg cfg = kiss_fft_alloc( nfft ,is_inverse_fft ,0,0 );
-
-        while ...
-        
-            ... // put kth sample in cx_in[k].r and cx_in[k].i
-            
-            kiss_fft( cfg , cx_in , cx_out );
-            
-            ... // transformed. DC is in cx_out[0].r and cx_out[0].i 
-            
-        free(cfg);
-
-    Note: frequency-domain data is stored from dc up to 2pi.
-    so cx_out[0] is the dc bin of the FFT
-    and cx_out[nfft/2] is the Nyquist bin (if exists)
-
-    Declarations are in "kiss_fft.h", along with a brief description of the 
-functions you'll need to use. 
-
-Code definitions for 1d complex FFTs are in kiss_fft.c.
-
-You can do other cool stuff with the extras you'll find in tools/
-
-    * multi-dimensional FFTs 
-    * real-optimized FFTs  (returns the positive half-spectrum: (nfft/2+1) complex frequency bins)
-    * fast convolution FIR filtering (not available for fixed point)
-    * spectrum image creation
-
-The core fft and most tools/ code can be compiled to use float, double,
- Q15 short or Q31 samples. The default is float.
-
-
-BACKGROUND:
-
-    I started coding this because I couldn't find a fixed point FFT that didn't 
-use assembly code.  I started with floating point numbers so I could get the 
-theory straight before working on fixed point issues.  In the end, I had a 
-little bit of code that could be recompiled easily to do ffts with short, float
-or double (other types should be easy too).  
-
-    Once I got my FFT working, I was curious about the speed compared to
-a well respected and highly optimized fft library.  I don't want to criticize 
-this great library, so let's call it FFT_BRANDX.
-During this process, I learned:
-
-    1. FFT_BRANDX has more than 100K lines of code. The core of kiss_fft is about 500 lines (cpx 1-d).
-    2. It took me an embarrassingly long time to get FFT_BRANDX working.
-    3. A simple program using FFT_BRANDX is 522KB. A similar program using kiss_fft is 18KB (without optimizing for size).
-    4. FFT_BRANDX is roughly twice as fast as KISS FFT in default mode.
-
-    It is wonderful that free, highly optimized libraries like FFT_BRANDX exist.
-But such libraries carry a huge burden of complexity necessary to extract every 
-last bit of performance.
-
-    Sometimes simpler is better, even if it's not better.
-
-FREQUENTLY ASKED QUESTIONS:
-	Q: Can I use kissfft in a project with a ___ license?
-	A: Yes.  See LICENSE below.
-
-	Q: Why don't I get the output I expect?
-	A: The two most common causes of this are 
-		1) scaling : is there a constant multiplier between what you got and what you want?
-		2) mixed build environment -- all code must be compiled with same preprocessor 
-		definitions for FIXED_POINT and kiss_fft_scalar
-
-	Q: Will you write/debug my code for me?
-	A: Probably not unless you pay me.  I am happy to answer pointed and topical questions, but 
-	I may refer you to a book, a forum, or some other resource.
-
-
-PERFORMANCE:
-    (on Athlon XP 2100+, with gcc 2.96, float data type)
-
-    Kiss performed 10000 1024-pt cpx ffts in .63 s of cpu time.
-    For comparison, it took md5sum twice as long to process the same amount of data.
-
-    Transforming 5 minutes of CD quality audio takes less than a second (nfft=1024). 
-
-DO NOT:
-    ... use Kiss if you need the Fastest Fourier Transform in the World
-    ... ask me to add features that will bloat the code
-
-UNDER THE HOOD:
-
-    Kiss FFT uses a time decimation, mixed-radix, out-of-place FFT. If you give it an input buffer  
-    and output buffer that are the same, a temporary buffer will be created to hold the data.
-
-    No static data is used.  The core routines of kiss_fft are thread-safe (but not all of the tools directory).
-
-    No scaling is done for the floating point version (for speed).  
-    Scaling is done both ways for the fixed-point version (for overflow prevention).
-
-    Optimized butterflies are used for factors 2,3,4, and 5. 
-
-    The real (i.e. not complex) optimization code only works for even length ffts.  It does two half-length
-    FFTs in parallel (packed into real&imag), and then combines them via twiddling.  The result is 
-    nfft/2+1 complex frequency bins from DC to Nyquist.  If you don't know what this means, search the web.
-
-    The fast convolution filtering uses the overlap-scrap method, slightly 
-    modified to put the scrap at the tail.
-
-LICENSE:
-    Revised BSD License, see COPYING for verbiage. 
-    Basically, "free to use&change, give credit where due, no guarantees"
-    Note this license is compatible with GPL at one end of the spectrum and closed, commercial software at 
-    the other end.  See http://www.fsf.org/licensing/licenses
-
-    A commercial license is available which removes the requirement for attribution.  Contact me for details.
-
-  
-TODO:
-    *) Add real optimization for odd length FFTs 
-    *) Document/revisit the input/output fft scaling
-    *) Make doc describing the overlap (tail) scrap fast convolution filtering in kiss_fastfir.c
-    *) Test all the ./tools/ code with fixed point (kiss_fastfir.c doesn't work, maybe others)

-If you are reading this, it means you think you may be interested in using the SIMD extensions in kissfft 
-to do 4 *separate* FFTs at once.
-
-Beware! Beyond here there be dragons!
-
-This API is not easy to use, is not well documented, and breaks the KISS principle.  
-
-
-Still reading? Okay, you may get rewarded for your patience with a considerable speedup 
-(2-3x) on intel x86 machines with SSE if you are willing to jump through some hoops.
-
-The basic idea is to use the packed 4 float __m128 data type as a scalar element.  
-This means that the format is pretty convoluted. It performs 4 FFTs per fft call on signals A,B,C,D.
-
-For complex data, the data is interlaced as follows:
-rA0,rB0,rC0,rD0,      iA0,iB0,iC0,iD0,   rA1,rB1,rC1,rD1, iA1,iB1,iC1,iD1 ...
-where "rA0" is the real part of the zeroth sample for signal A
-
-Real-only data is laid out:
-rA0,rB0,rC0,rD0,     rA1,rB1,rC1,rD1,      ... 
-
-Compile with gcc flags something like
--O3 -mpreferred-stack-boundary=4  -DUSE_SIMD=1 -msse 
-
-Be aware of SIMD alignment.  This is the most likely cause of segfaults.  
-The code within kissfft uses scratch variables on the stack.  
-With SIMD, these must have addresses on 16 byte boundaries.  
-Search on "SIMD alignment" for more info.
-
-
-
-Robin at Divide Concept was kind enough to share his code for formatting to/from the SIMD kissfft.  
-I have not run it -- use it at your own risk.  It appears to do 4xN and Nx4 transpositions 
-(out of place).

-Changes from version 1.6.38 to version 1.6.39
+Changes from version 1.6.42 to version 1.6.43
 ---------------------------------------------
 
- * Changed the error handler of oversized chunks (i.e. larger than
-   PNG_USER_CHUNK_MALLOC_MAX) from png_chunk_error to png_benign_error.
- * Fixed a buffer overflow error in contrib/tools/pngfix.
- * Fixed a memory leak (CVE-2019-6129) in contrib/tools/pngcp.
- * Disabled the ARM Neon optimizations by default in the CMake file,
-   following the default behavior of the configure script.
- * Allowed configure.ac to work with the trunk version of autoconf.
- * Removed the support for "install" targets from the legacy makefiles;
-   removed the obsolete makefile.cegcc.
- * Cleaned up the code and updated the internal documentation.
+ * Fixed the row width check in png_check_IHDR().

+Historical notes
+----------------
+
+The libpng library has been in extensive use and testing since mid-1995.
+Version 0.89, published a year later, was the first official release.
+By late 1997, it had finally gotten to the stage where there hadn't
+been significant changes to the API in some time, and people have a bad
+feeling about libraries with versions below 1.0.  Version 1.0.0 was
+released in March 1998.
+
+Note that some of the changes to the `png_info` structure render this
+version of the library binary incompatible with libpng-0.89 or
+earlier versions if you are using a shared library.  The type of the
+`filler` parameter for `png_set_filler()` has changed from `png_byte`
+to `png_uint_32`, which will affect shared-library applications that
+use this function.
+
+To avoid problems with changes to the internals of the `info_struct`,
+new APIs have been made available in 0.95 to avoid direct application
+access to `info_ptr`.  These functions are the `png_set_<chunk>` and
+`png_get_<chunk>` functions.  These functions should be used when
+accessing/storing the `info_struct` data, rather than manipulating it
+directly, to avoid such problems in the future.
+
+It is important to note that the APIs did not make current programs
+that access the info struct directly incompatible with the new
+library, through libpng-1.2.x.  In libpng-1.4.x, which was meant to

+`info_struct` can still be accessed, but the compiler will issue a

- * You might want to use it where:
- *
- * - you want to rename a function "out of the way" so that you could replace
- *   a function with a different version (the original version would still be
- *   in the library just with a different name - so you could debug the new
- *   version by comparing it to the output of the old)
- *
- * - you want to rename all the functions to versions with a suffix so that 
- *   you can include two versions of the library and choose between functions
- *   at runtime.
- *
- *     e.g. omxIPBM_Copy_U8_C1R could be renamed omxIPBM_Copy_U8_C1R_CortexA8

- *     x[n] = SUM[k=0,...,N-1] X[k].e^(jnk.2.pi/N)
- *     n=0,1,2,...N-1
- *     N=2^order.

- * Description:
- * Twiddle table for Forward FFT in float format.
- * It contains complex pairs [-cos (W * i), -sin (W * i)] where W = -2*PI/N
- * and 0<= i<= N/8.  N is the max size of the FFT. Here N = 2^12
- * Values for N/8 < i < N are generated in the FFTInit function using the
- * symmetries of cos and sine.
- *
- * We use the negative to be consistent with the S32 version.
