# IPTC profile not always wrapped properly inside an 8BIM profile.
# TIFF tile geometry must be divisible by 16.
# Rename of SincPolynomial to SincFast for easier user understanding
# Ditto for LanczosChebyshev to LanzcosFast
# Switch default resize filters to using the faster SincPolynomial filter by default internally. However 'Sinc' will stil use the Trigonometric function, and can be used to assign the trig version of Sinc() to filters using the filter expert options.
# Removed the default filter for 'distort' was found to be a very blurry inaccurate filter function. It was removed and replaced with a correct Gussian filter (as used by resize)
# Added a switch so that "-interpolate filter" will force the use of a cylindrical filter for ALL pixels in distorted images. That is you can use that switch to use a cylindrical filter even for images that are being enlarged by the distortion. It is slightly slower though. However EWA is still currently using a fixed 2.0 sampling radius. This switch complements the use of "-filter point" which turns off EWA filters in favor of interpolation for all pixels in a distorted image. BOTH switched should not be used together.
# A bug in the support radius of the EWA resampling function was found, now that correctly defined resize filters are being used. Suddenly Normal Gaussian distortions are not so blurry, and tests with distortions of the 'Rings' image show extremely good and clear results, with only minimal blurring. The filter 'blur' expert option can be used to adjust this further.
# Don't negate the geometry offset for the -extent option.

# Don't allow resize filter weights to go to zero (reference http://www.imagemagic...p?f=3&t=17132).
# Now that MagickPIL is a MagickRealType, some casts are unneeded.
# Do not break words if caption size is absolute (reference http://www.imagemagic...p?f=1&t=17123).
# Don't define HAVE_THREADS for --without-threads configure script option.
# Modified "magick/resize.c" so that MagickPIL is a MagickRealType number. Some computations were needlessly done in long double precision because PIL forced an automatic upcast wherever it appeared. Changed its name to MagickREALTYPEPI.
# Modified "magick/resize.c" so that Bohman uses one trig call + one sqrt call instead of two trig calls.
# modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
# Removed LanczosFast from supported filters (SincFast*SincFast is faster)
# If IPTC profile is not embedded in an 8bim resource, declare it IPTC rather than 8BIM.
# Support %[version] and %[copyright].
# Improve performance of the pixel cache.

# Chantal Racette double checked the bounding parallelogram computation in resample.c (and I tightened the comments).
# Temporary files not always deleted (reference http://www.imagemagic...p?f=2&t=15960).
# Simplified the ClampUpAxes code, the use of its outputs, its comments, and credited Craig DeForest for the "clamp singular values" idea.
# No reason to have "insane" precision Sinc in resize.c: Use the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
# Replace the blurry "High Quality EWA" technique with a 'Clamped EWA' for Distort Resampling. This makes -distort a whole lot nicer and allows for the use of better cylindrical filters.
# Bug fix for -filter point distorts (occasional generating black pixels)
# Fix Point filter for ResizeImage() caused by support limiting the Box weighting function.

• Fix memory assertion with --enable-embeddable (reference http://www.imagemagic...p?f=3&t=17201).
• Don't permit access to pixels when pinging an image (reference http://www.imagemagic...p?f=3&t=17194).
• Added sqrt(2) bluring default for Gaussian Filter if used as a Cylindrical EWA filter. This resulted in the last aliasing issue that was present in tests for Gaussian EWA resampling. However it is still a very blury filter for default use in EWA.
• Adjusted Variable Mapping Blur Composition so user arguments actual relate properly to the sigma of the blur for a maximum mapping value.
• Fix horizon anti-alising for output scaled perspective distortions.
• 'Bessel' filter is nor offically and more accuritally named 'Jinc' however 'Bessel' while not visible as a filter option can still be used as an internal alias for 'Jinc'.

• Autodetect file type support in Makefile.PL to prevent test failures
• Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24) http://www.gson.org/t...ing-thesis.pdf
• Added filter "Robidoux" whcih is a 'negativally' blurred version of the "Lanczos2D" filter specifically designed to be less 'blurry' for horizontal and vertical lines in no-op distortions. It is now the default filter (if none specified) for EWA resampling.
• Add support for "pattern:vertical2" and "pattern:horizontal2".
• Add support for "pattern:vertical3" and "pattern:horizontal3".
• Properly handle PSD layers with negative offsets.

# Ignore PS bounding box offsets if -page is set.
# Use #pragma omp master for dumping single threaded debugging information (single caused a fault).
# Add support for -evaluate exp.
# Added "filter:sigma" expert setting defining the 'sigma' for the Gaussian filter only. This is similar in action to 'blur' but only for Gaussians, and does not modify the filters support, allowing you to set a very small sigma, without the function 'missing' all pixels. (This will allow future adjustment of Gaussians for variable blur mapping)
# Patch for DrawableRotation() and DrawableTranslation() (reference http://www.imagemagic...p?f=3&t=17246).
# The webp format requires the webpconv delegate program (experimental).
# Replaced "Robidoux" with Cubic 'Keys' filter that is near equivelent to the previous sharped "Lanczos2D" filter. (C=0.31089212245300069) This also is very similer to a Mitchell filter but specifically designed for EWA use and is the new default filter for Distorting Images.
# Original sharpened Lanczos2D filter now called "Lanczos2Dsharp"
