7c4ef88dab Remove unused functions FontUtils::GetAllRenderableCharacters
They used the function pango_coverage_max which does nothing and
which has been deprecated since pango version 1.44.

eb8f1674bf Correct "NoImages" in debug pdf file
Issues:
  Debug information for "NoImages" just be binary image,
  it don't show up the result of photo_mask_pix to developer

Fix:
  Substract binary image to photo_mask_pix, the result
  are "NoImages" binary pix

640c14e080 AutoPageSeg/FindBlocks/GridRemoveUnderlinePartitions: avoid self-deletion
When checking horizontal line partitions for
possible interpretation as underline formatting,
avoid confusing the hline partition itself with
an overlapping neighbour (which would delete it).

65a077d3e9 FindAndRemoveLines/FindVerticalAlignment: decrease fixed vline min length
When detecting vertical separators, the blob aligner is used to glue
line segments (often segmented due to artificial cracks).
But (unlike LineFinder) it has many parameters that are not
relative to pixel density/resolution.
This change decreases the minimum absolute length in pixels
for vertical separators.

578462109b Remove unused char constant that causes a warning.
The kDictWildcard is never actually used, so removing it makes
no difference. It causes warnings in MSVC builds as MSVC doesn't
know how to pack a unicode value into chars.

In particular, "defined but not used" (caused by GRAPHICS_DISABLED),
double constants being truncated to floats, and implicit casts.

Fix Memory leak when using TESSERACT_IMAGEDATA_AS_PIX

7f45b719d1 Fix Memory leak when using TESSERACT_IMAGEDATA_AS_PIX
If building with TESSERACT_IMAGEDATA_AS_PIX, then tesseract
doesn't compress/decompress images, but rather holds the
data as internal Pix structures. Unfortunately, I forgot to
make the ImageData destructor free these, so memory leaked
during use. Fixed here.

548a832b98 Use strtok_s for MSVC in class SVNetwork
strtok_s can be used with MSVC as a replacement for strtok_r, so less
special handling is needed in the code and class SVNetwork can be
made smaller by removing member has_content.

cb3880fb15 Disable more code and data with GRAPHICS_DISABLED
Some runtime parameters which are only relevant with graphics enabled
were now removed from builds when graphics was disabled.

TableFinder::DisplayColSegmentGrid is never used, so remove it completely.

Builds with --disable-graphics significantly reduce the code size and avoid
some function calls which might be important for certain applications:

   text	   data	    bss	    dec	    hex	filename
3219230	  41136	  13920	3274286	 31f62e	.libs/libtesseract.so (--disable-graphics, old)
3211347	  40976	  13600	3265923	 31d583	.libs/libtesseract.so (--disable-graphics, new)
3360942	  43656	  15392	3419990	 342f56	.libs/libtesseract.so (default)

22e6c2e5a7 Fix division by 0.0 in BaselineRow::PerpDistanceFromBaseline
It was reported by oss-fuzz (issue 23962).

Add log output to find real images which trigger that issue.
Avoid also some conversions from float to double by always using float.

It also removes STRING from osdetect.h and serialis.h.
