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

150e2e54fe Squash some warnings in MSVC build. 
In particular, "defined but not used" (caused by GRAPHICS_DISABLED),
double constants being truncated to floats, and implicit casts.

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)

8137cf35a6 Use const char* for filename parameters 
This replaces the proprietary STRING data type
(801 instead of 838 lines remaining).

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

If api->Init is called with OEM_DEFAULT in DISABLED_LEGACY_ENGINE
build modes, the engine mode is never set, resulting in no

Robert Schubert
5b976bfb55 fix langdata (user words/patterns) file suffixes for LSTMs: 
- add another constructor for LSTMRecognizer
  which takes the language_data_path_prefix configured/selected
  at runtime and passes it to the internal CCUtil
- use this in Tesseract::init_tesseract_lang_data when LSTMs
  are available

(this was missing from 297d7d86ce)
