* Fix memory leak in text annotation.
* The "-strip" option was excluding the PNG tRNS chunk.
* Caption now wraps properly for Chinese text.
* The PNG encoder would sometimes fail to respect the -define
PNG:color-type option when the incoming image was PseudoClass.
* Properly handled continued JPEG embedded profiles.
* Revert -colorspace sRGB option patch.
* Revert -type PaletteMatte option patch.
* etc. see ChangeLog.

* Defend against corrupt PSD resource blocks.
* Properly allocate points when render text with large font size.
* Added support for Z_RLE strategy in the png compressor, using
-quality 98 or 99.
* Handle "-quality 97" properly in the png encoder, i.e., use intrapixel
filtering when writing a MNG file and no filtering when writing a PNG file.
* Added "-define PNG:compression-level|strategy|filter=value" options to
the PNG encoder. If these options are used, they take precedence over
the -quality option.
* Use zlib default compression strategy instead of Z_RLE and Z_FIXED
strategies when linking with zlib versions (prior to 1.2.0 and 1.2.2.2,
respectively) that don't support them.

* added Initial implementation of Cylinder to/from Plane 3D Distorts
Includes deritive (scaled lookup), and anti-alised horizon (validity)
Currently can NOT handle extractions from full 360 cylinder panoramas.
* Fix transient error for composite over operator.
* Fix one-off bug in option parser.
* etc., see ChangeLog
- inc-struct.diff seems to be redundant to me, removing

* The -scale option nows considers the alpha channel when scaling.
* Don't use comma as a separator for stroked tex.
* Fix transient bug for HSL to RGB and back.
* Fixed PNG8 reduction to work with an image that reduces to 256 colors
plus transparency, by merging the two darkest red colors.
* etc., see ChangeLog

* Revised PNG palette optimization
* Added some debug logging in coders/png.c.
* More precise blur values for Lanczos2Sharp and LanczosSharp.
* Added location of first Mitchell crossing (=8/7) to the filters data
structure.
* Added Lanczos2D* filters now named Lanczos2*
* Reorganization of AcquireFilter() to make it work better
* Clearer EWA filters (LanczosSharp etc) comments.
* Added LanczosSharp (3-lobe Lanczos with sharpening)
* Filter sharpening factors are also always applied regardless of usage.
* CubicBC filter formulas simplified by constant folding. In
particular, P1 coefficient (always zero) removed from coeff.
* Revert the Robidoux filter to a Keys cubic with C=(108 sqrt 2-29)/398
(as already specified in the documentation).
* Ignore PS bounding box offsets if -page is set.
* 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.
* Patch for DrawableRotation() and DrawableTranslation()
* 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.
* 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/thesis/warping-thesis.pdf
* Added filter "Robidoux" which is a slightly sharpened version of the
"Lanczos2D" filter (blur=0.958033808) specifically designed to be less
'blurry' for horizontal and vertical lines in no-op distortions.
* Add support for "pattern:vertical2" and "pattern:horizontal2".
* Add support for "pattern:vertical3" and "pattern:horizontal3".
* Properly handle PSD layers with negative offsets.
* Added sqrt(2) bluring default for Gaussian Filter if used as
a Cylindrical EWA filter. This resulted removing the last aliasing
issue that was present in tests for Gaussian EWA resampling. Of course
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 now offically and more accuritally named 'Jinc'
however 'Bessel' while not visible as a filter option can still be used
OBS-URL: https://build.opensuse.org/package/show/graphics/ImageMagick?expand=0&rev=45
* Automatically set the quantum depth to 16 for HDRI.
* 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 still use the
Trigonometric function, and can be used to assign the trig version
of Sinc() to filters using the filter expert options.
* The default filter for 'distort' was found to be a very blurry inaccurate
filter function. It was removed and replaced with a correct Gaussian
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. 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 switches 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.
* The RGBO format is now listed as a supported format.
* Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
