aba1800f69 Round output buffers for intSimdMatrix.
In order to allow intSimdMatrix implementations to 'overwrite'
their outputs, ensure that the output buffers are always padded
to the next block size.

This doesn't make any difference yet, but it enables optimisations
further down the line, especially when the biasing is pulled into
the SIMD.

9dfdac51c6 Tweak scales array for intSimdMatrix case.
Currently, the size of the scales array is not rounded up
in the same way as the weights are. This blocks us pushing
the scale calculations into the SIMD, as when we "overread"
the end of the scale array, we potentially get errors.

Here, we adjust the intSimdMatrix stuff to ensure that the
scales array reserves enough entries to allow such overreads
to work.

This doesn't make any difference for now, but opens the way
for future optimisations.

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.

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)
