The previous implementation didn't include all possible JPEG file
signatures. All signatures in the range of ff d8 ff e0 and ff d8 ff ef
should be valid, in addition to ff d8 ff db (no application segment).
See <https://gist.github.com/leommoore/f9e57ba2aa4bf197ebc5?permalink_comment_id=3863054#gistcomment-3863054>

This will prevent unnecessary conversion of units.

[API change] New Avif constructor on ImageType.

Text.Pandoc.ImageSize: Add `Webp` constructor on ImageType. [API change]

...with width/height. That was a mistaken call in #6936.
Usually when these values disagree, it is because the image
has been resized by a tool that leaves the original exif values
the same, so the width/height metadata are more likely to be
correct that exif width/height.
Closes #9871.

Otherwise our code can fail to determine image size.

[Minor API change]
This allows pandoc to get size information from tiff images.
Closes #7405.

..and add new definitions isomorphic to xml-light's, but with
Text instead of String. This allows us to keep most of the code in
existing readers that use xml-light, but avoid lots of unnecessary
allocation.
We also add versions of the functions from xml-light's
Text.XML.Light.Output and Text.XML.Light.Proc that operate
on our modified XML types, and functions that convert
xml-light types to our types (since some of our dependencies,
like texmath, use xml-light).
Update golden tests for docx and pptx.
OOXML test: Use `showContent` instead of `ppContent` in `displayDiff`.
Docx: Do a manual traversal to unwrap sdt and smartTag.
This is faster, and needed to pass the tests.

This exports functions that uses xml-conduit's parser to
produce an xml-light Element or [Content]. This allows
existing pandoc code to use a better parser without
much modification.
The new parser is used in all places where xml-light's
parser was previously used. Benchmarks show a significant
performance improvement in parsing XML-based formats
(especially ODT and FB2).
Note that the xml-light types use String, so the
conversion from xml-conduit types involves a lot
of extra allocation. It would be desirable to
avoid that in the future by gradually switching
to using xml-conduit directly. This can be done
module by module.
The new parser also reports errors, which we report
when possible.
A new constructor PandocXMLError has been added to
PandocError in T.P.Error [API change].
Closes #7091, which was the main stimulus.
These changes revealed the need for some changes
in the tests. The docbook-reader.docbook test
lacked definitions for the entities it used; these
have been added. And the docx golden tests have been
updated, because the new parser does not preserve
the order of attributes.
Add entity defs to docbook-reader.docbook.
Update golden tests for docx.

This change allows pandoc to extract size information
from more SVGs. Closes #7045.

After the move to JuicyPixels, we were getting incorrect
width and heigh information for some images (see #6936, test-3.jpg).
The correct information was encoded in Exif tags that
JuicyPixels seemed to ignore. So we check these first
before looking at the Width and Height identified by
JuicyPixels.
Closes #6936.

...for png, jpeg, gif, instead of doing our own binary parsing.
See #6936.

This shouldn't happen, in general, but it can happen with
JPEGs that don't conform to the spec. Having a DPI of 0
will blow up size calculations (division by 0).
Closes #6880.

* Use implicit Prelude
The previous behavior was introduced as a fix for #4464. It seems that
this change alone did not fix the issue, and `stack ghci` and `cabal
repl` only work with GHC 8.4.1 or newer, as no custom Prelude is loaded
for these versions. Given this, it seems cleaner to revert to the
implicit Prelude.
* PandocMonad: remove outdated check for base version
Only base versions 4.9 and later are supported, the check for
`MIN_VERSION_base(4,8,0)` is therefore unnecessary.
* Always use custom prelude
Previously, the custom prelude was used only with older GHC versions, as
a workaround for problems with ghci. The ghci problems are resolved by
replacing package `base` with `base-noprelude`, allowing for consistent
use of the custom prelude across all GHC versions.

* Update copyright year
* Copyright: add notes for Lua and Jira modules

* Avoid duplicating the dash case
* Pull common functions out of case branches
* Make sure list lengths are only calculated once
* Use unless
* Simplify parseURIReference' and avoid an unnecessary call to length
* Use <$> instead of reimplementing it
* Use swap instead of reimplementing it
* Remove eta-expansion that's been unnecessary since 90f5dd8
* Use tailDef instead of reimplementing it
* Use second instead of fmap, per @tarleb

PR #5884.
+ Use pandoc-types 1.20 and texmath 0.12.
+ Text is now used instead of String, with a few exceptions.
+ In the MediaBag module, some of the types using Strings
were switched to use FilePath instead (not Text).
+ In the Parsing module, new parsers `manyChar`, `many1Char`,
`manyTillChar`, `many1TillChar`, `many1Till`, `manyUntil`,
`mantyUntilChar` have been added: these are like their
unsuffixed counterparts but pack some or all of their output.
+ `glob` in Text.Pandoc.Class still takes String since it seems
to be intended as an interface to Glob, which uses strings.
It seems to be used only once in the package, in the EPUB writer,
so that is not hard to change.

(#5383)
This fix ignores all whitespace in the PDF /MediaBox line so that a wider range of PDF sizes can be read. This improves fix to #4322.

The haddock module header contains essentially the
same information, so the boilerplate is redundant and
just one more thing to get out of sync.
|
|
Quite a few modules were missing copyright notices.
This commit adds copyright notices everywhere via haddock module
headers. The old license boilerplate comment is redundant with this and has
been removed.
Update copyright years to 2019.
Closes #4592.

- Export `inEm` from ImageSize [API change].
- Change `showFl` and `show` instance for `Dimension` so
extra decimal places are omitted.
- Added `Em` as a constructor of `Dimension` [API change].
- Allow `em`, `cm`, `in` to pass through without conversion
in HTML, LaTeX.
Closes #3450.

The old code made some unwise assumptions about
