"<div>abc <![CDATA[d<e&>f]]> ghi</div>" will now add into
the DOM 3 text nodes: "abc " , "d<e&>f" and " ghi", as it's
supposed to happen in XML/XHTML.
(In HTML, browsers would not do any specific parsing, with
possibly strange results. We do it too in plain HTML.)

…& cleanups' by NiLuJe

* Mark getter functions as const
* We don't need stbiw outside of lvimg
(Probably requires a recent stbiw, the one shipped w/ NanoSVG is
hilariously old. Harmless if unsupported, though).

And make it private & inlined, as only lvtinydom uses it.

…ivate header.

* Move ldomPack/ldomUnpack to the CacheFile class, as that the only
  class that uses it.
* Which implies duplicating (zlib) unpack in PDBFile for pdbfmt...
* Lazy init ZSTD ressources, and keep 'em around as long as sensible.

* crengine: allow to set global cache compression type (none, zlib, zstd).
* crengine: allow use zlib cache compression even if zstd available
  (selected by setCacheCompressionType() global functions).
  In the future, can be implemented selection in the settings dialog.

* Android: add static library zstd to dependencies.

It turns out it's not just LVImg that wants inverted alpha: it's *all* CRe...
So, we'll be handling the pixel format conversion entirely in KOReader instead, as dealing with the alpha here is kind of hairy without basically rewiring all the things.

:(

…oid RGBA.

Conversion time was reduced by about 50%:
Nokia 8: 18 ms => 9 ms
x86 emu: 1.6 ms => 0.6 ms

Handle content as text, but don't stop just at any '<',
only at '</script>', as <script> may contain tags.
Not doing that might put a lot of javascript as
document text content. Note that <script> content
is "display: none" by default.

Upstream update of the German patterns (roughly 800 changes)

(from cr3gui/data/hyph/german_hyphen.pattern).

It was hardcoded'ly removed as part of 9214bfc when
implementing support for CSS width & height for images,
so they don't get in the way.
Removed the hardcoding so the original CoolReader
settings can work again.
We can still disable that from frontend code.

Increase nb of bitmaps from 2 to 3 lUInt32 as we're
going over 64 properties.

Compute image size according to CSS2 specs, ensuring
CSS width, height, min-width, min-height, max-width
and max-height.
Used in lvtextfm when drawing images, and when
estimating block widths in getRenderedWidths()
instead of the previous wrong computation.
Limitation: heights in % are not supported and ignored.

Ensure min-width, min-height, max-width (but not max-height)
on block elements, inline-block/table, block floats and
floating images (min-height in % not supported).
Ensure min-width on the table element itself (but not
supported on the table inner elements like cells and cols).

So frontends can know if the rendering or the number
of pages have changed (instead of relying of the
document height, which is not a strictly accurate
indicator of changes).

Related to 52eb1ad.

Ensure "the rules above are applied again" from the specs
when ensuring max/min-height, meaning some bits of the width
computations have to be ensured again.

Also handle <image> just as <img> in the few places we
did not yet: when handling floats.

Quite often seen in EPUBs (may be generated by some
Calibre plugin) to force an image to scale to the
page (100%) while keeping aspect ratio.
(Positionning is not ensured: horizontal centering may
be via the publisher CSS, but vertical centering can't
and is not ensured.)

An image having its bottom on the baseline, don't
account for the strut added space below when this
space would be negative (ie. with line-height: 0,
which might be explicitely used to kill that strut
added bottom blank space).

Measured widths could be wrong when other unicode space
chars are used, which should not collapse.

Since 25d1ce2, lengthToPx() can access the document
and get the root font size. But we need to pass it
to lvpagesplitter though.

Sidebar: this is what templates are for.

Code probably not exercised much of anywhere, definitely not in
KOReader.

Fix #412

As discussed in #409

Basically:

* If !arbitraryImageScaling: try integer scaling, from maxScaleMult to
  1. If nothing fits the bounding box, fall back to arbitrary scaling.
  Get rid of the weird mutlitplier and magic scratch pixels, because
  when they weren't introducins egregious errors, they were actually
  *introducing* rounding errors!
* Simplify the classic scaling code, based on Qt's algorithm.

No floats or weird multiplier needed, because we *always* MUL before we
DIV.
And if no rounding was deemed necessary by Qt, then implicit truncation
is probably good enough for us, too ;).

Avoid '</sc' at buffer end to miss matching '</script>' if
it would come next when reading from file stream.
A bit of clean up of this part of the code, added comments
as I understand what bits are supposed to do.

"en" and "en-US" do start with "en", but "eno" should not.

Proper parsing of "!important" at end of font-family.
Also try to handle "inherit" in the most compatible way,
even if not per current specs:
"inherit" is nowadays invalid when not standalone.
We have seen books with 'font-family: "Some Font", inherit',
that Calibre 3.x would render with "Some Font", while Firefox
and Calibre 5.x would consider the whole declaration invalid.
So, best to just ignore any non-standalone "inherit", and
keep parsing the font names.

Mentionned in early specs of EPUB3 (and later deprecated), or
only supported as -webkit- at some point in the past, so these
can be found in some books without the newer alternatives.

Replace LTEXT_HIDDEN and have "visibility: hidden" use it.
This might allow adding support for rare CSS text
properties (like "visibility", "line-break) without
wasting a bit in the LTEXT_ flags.
Have any generated content (list item markes, pseudo
elements, BiDi markers) pass their originated node
to AddSourceLine() so we always have access to the
node to fetch these extra properties.

…171 'LVImg: Simplify JPG & PNG decoding' by NiLuJe

* Avoid unnecessary per-scanline allocs in PNG

It was working somehow as we mostly use them with count=1,
but it was wrong when count >=2.

Follow up to 5330750: when getting a non-boxing parent
or child, be sure we actually get one (as we can have
nested boxing elements, like tabularBoxes with completed
incomplete tables).

When there are multiple font names in a list (ie, with
CSS 'font-family: "Font1", "Font2"', multiple fonts may
get the same higher score. We keep the first best match
in the loop, but at the end, we prefer an instantiated
font to a not yet instantiated one with the same match.
Depending on various things, it may not be the first one.
So, provide an additional weight to font by their order
in the list.

Fix accounting of erm_final rendering by not ignoring those
done in sub-flows/contexts (floats, inline-blocks, tables).

To be consistent, as it will be drawn with these rend_flags.

Use the cells max content width as the column widths
when all these max widths fit (instead of using some
heuristics about the sum of the means, which could
lead to uneeded smaller widths and wraps).

Allow parsing color value "currentcolor".
Can be used with "color:" and "background-color:" even if
useless, but it is the initial value for border-color,
and the default when no color value is found in "border:"
(ie. "border: solid thin").

Represents the width, or more precisely the advance measure,
of the glyph "0" (zero) in the element's font.
In the cases where it is impractical to determine, it must
be assumed to be 0.5em wide by 1em tall.
So, let's handle it just as 'ex', assuming 0.5em.

Allow transparent SVG images to blend, instead
of drawing them on a white background.

Based on koreader/crengine#441: 604132a303a3118a8a95322a7e344fc1b7bd4580 'LVFntMan: Ensure proper alignment of the glyph bitmap buffer in LVFon…' by NiLuJe

In 'img src="..."' and 'background-image: url(...)', where
we support "data:image/svg;base64,...", also support
a non-standard "data:image/svg;-cr-plain,...".
May be used to build SVG images at rendering time, and
have the code set them as attribute or styles (will be
useful to generate the MathML <msqrt> radical symbol).

When checking selectors, we normally skip/enter/exit
internal boxing elements when waking parents or siblings.
This allows having selectors specifying one type of
internal boxing elements - and so not skip them.
Adds in advance a new internal elements: <mathBox>,
which will be used for MathML support (which will
use CSS selectors to do some part of its work).

As only us (and not publishers) can set widths on them,
ensure them even if we normally don't on table sub-elements.

Allows measuring the area taken by ink (glyphs, borders,
images...) by just using the regular drawing code.
(Easier than doing it using font and glyphs metrics...)

Everything wrapped in #if MATHML_SUPPORT==1 / #endif,
mostly for documentation purpose, to make it explicite
a reader can skip it when not interested.

lvtinydom.cpp DOM writers: add flag when entering <math>,
so that MathMLHelper can complete and tweak the DOM as it
is being built.

lvrend.cpp: as most of the non trivial MathML elements
(mfrac, msub, mover, msqrt...) are handled as inline-table,
plug a few specific handler in the table rendering code,
and in getRenderedWidths() to estimate inline-block/table
elements min/max widths.
Also have setNodeStyle() call setMathMLElementNodeStyle()
on MathML elements to complete their styling.

lvtextfm.cpp: alignLine() position inline-block boxes
may call a specific method on MathML elements to tweak
their position and size to ensure vertical stretching
of MathML operators, so they adjust to the line box
vertical space, adjusting the line height and baseline.

lvrend.cpp renderFinalBlock() and lvtextfm.cpp: pass
LTEXT_MATH_TRANSFORM flag to have stretchy final
blocks drawn stretched.

Simple (and ugly) way to draw MathML stretchy operators,
for fences, arrows, ... to adjust to their neighbours.
A more correct rendering would require more changes
here and in lvtextfm.cpp, to use OT Math fonts glyph
variants and glyph construction features.

DrawStretchedGlyph(): fix synthesized bold italic drawing

getCharProp() is nearly no longer used when using libunibreak,
but it is still used by lStr_findWordBounds() to detect words
to try to hyphenate.
It knowing only about latin, greek and cyrillic letters made
hyphenation not detect any candidate word in Armenian and
Georgian text.
So, fallback to use utf8proc to detect letters in any other
alphabet so hyphenation (including soft-hyphens) can work.
Also detect RTL chars, as we don't want to hyphenate on
soft-hyphens in Arabic or Hebrew, as the text rendering code
currently can't draw hyphens on the left.
