bump crengine:
Allow for quicker loading when interested in metadata only.
Allow for more than 65535 different attribute values.
Increase gamma values range.
Bump crengine for cache re-use fix and warnings when
cache sizes reached.
Allow for increasing some crengine cache sizes with a new
setting: "cre_storage_size_factor" = 1.5 (or 2, or 4...)
With ["cre_compress_cached_data"] = false in settings.reader.lua.
Not using compression for cache files does indeed take more space,
but it does speed up opening, rendering, page turns, and closing,
with big documents.
Bump base and crengine.
cre:loadDocument() may fail in recognizing the document format, and
koreader would previously keep calling other methods on it, which would
make crengine segfaults. We now check loadDocument success at the
various places it is called, and try to deal the best way we can when it fails.
This is done by/for kosync plugin at each opening, because
the docsettings was re-opened and saved for this, but later
overwritten by the current koreader docsettings - so it was
redone each time. This correctly adds this partial_md5_checksum
to the current koreader docsettings, which will be saved on
document closing - so it will not be redone next time.
Note: this partial_md5_checksum is not (yet) used by anything.
Avoid unnecessary work in ReaderView:onSetViewMode() and
ReaderRolling:updatePos() that would result in TOC being reset
and rebuilt (which can take time on books with huge TOC) during
reader setup.
* Allow for colored rendering
Available with all engines (CRE, PDF, Images).
Needs to manually add setting: "color_rendering" = true
* Disable color for djvudocument
* Use Screen:isColorEnabled()
* Bump base
Base bumped.
Previsouly, parts of document in <p style="font-family: serif">
would be rendered with the first font set, and would not
follow change of font (unline other texts without styles).
That was observable with Embedded Styles set to On, but is even
more noticiable with the new Embedded Fonts setting set to off.
Just under the existing "Embedded Styles". Support for this
was already there in crengine, and interfacing is similar to
what is done with Embedded Styles.
So an image file can have a cover in coverbrowser's display.
It also allows for an alternative viewer (ImageViewer widget)
when holding on file / View full size cover.
They may already be available (with other statistics stuff) under
the 'stats' key, but not if Statistics plugin is disabled. As this
plugin may be migrated to SQLite, readerui and readerfooter will now
set two new properties: doc_props (containing all and only the metadata
returned by document:getDocumentProps()) and doc_pages (updated
by readerfooter on any display or font change).
PDF document: returns additional PDF properties: Keywords
and Subject (as Description).
CRE cache, hyphdict and fonts can be initialized only once
when first credocument is opened. Previously, they were
recreated for each document, and as previous instances were probably
not free'd, this caused memory leaks.
When such blank page has only a few black pixels (dust), it would result in
a really small cropped area, than when scaled to fit screen, would cause a
crash with :
./ffi/mupdf.lua:63: could not allocate pixmap:
malloc of array (451342 x 612558 bytes) failed (integer overflow) (1)
Fix similar to what is done in KoptInterface:getAutoBBox(): when cropped area too small,
fall back to whole page (or here: to user's manually set area).

this should implement feature request of zoom mode for multi-columns
page in #501
This PR depends on koreader/koreader-base#435
How to use?
1. Tap the top left corner of a PDF/Djvu page to get into the flipping
mode
2. Double-tap on text block will zoom in to that column
3. Double-tap on any area will zoom out to an overview of the page
4. repeat step 2 to focus to another page block
How does it work?
1. We first find the mask of text blocks in the page. (Pic 1)
2. Then we intersect page boxes with user tap to form a page block. (Pic 2)
3. Finally we zoom the page to the page block and center current view to
that block. (Pic 3)
