Log Message:
Update graphics/tesseract to 3.04.01.
Move to new home at Github. Clean up.

2015-02-17 - V3.04.01
- Added OSD renderer for psm 0. Works for single page and
  multi-page images.
- Improve tesstrain.sh script.
- Simplify build and run of ScrollView.
- Improved PDF output for OS X Preview utility.
- INCOMPATIBLE fix to hOCR line height information - commit
  134ebc3.
- Added option to build Tesseract without Cube OCR engine
  (-DNO_CUBE_BUILD).
- Enable OpenMP support.
- Many bug fixes.

2015-07-11 - V3.04.00
- Tesseract development is now done with Git and hosted at
  github.com (Previously we used Subversion as a VCS and
  code.google.com for hosting).
- Tesseract now requires leptonica 1.71 or a higher version.
- Removed official support for VS 2008.
- Added support for 39 additional scripts/languages, including:
  amh, asm, aze_cyrl, bod, bos, ceb, cym, dzo, fas, gle, guj, hat,
  iku, jav, kat, kat_old, kaz, khm, kir, kur, lao, lat, mar, mya,
  nep, ori, pan, pus, san, sin, srp_latn, syr, tgk, tir, uig, urd,
  uzb, uzb_cyrl, yid
- Major updates to training system as a result of extensive
  testing on 100 languages.
- New training data for over 100 languages
- Improved performance with PIC compilation option.
- Significant change to invisible font system in pdf output to
  improve correctness and compatibility with external programs,
  particularly ghostscript.
- Improved font identification.
- Major change to improve layout analysis for heavily diacritic
  languages: Thai, Vietnamese, Kannada, Telugu etc.
- Fixed problems with shifted baselines so recognition can recover
  from layout analysis errors.
- Major refactor to improve speed on difficult images, especially
  when running a heap checker.
- Moved params from global in page layout to tesseractclass.
- Improved single column layout analysis.
- Allow ocr output to multiple formats using tesseract command
  line executable.
- Fixed issues with mixed eng+ara scripts.
- Improved script consistency in numbers.
- Major refactor of control.cpp to enable line recognition.
- Added tesstrain.sh - a master training script.
- Added ability to text2image training tool to just list available
  fonts.
- Added ability to text2image to underline words.
- Improved efficiency of image processing for PDF output.
- Added parameter description for each parameter listed with
  'print-parameters' command line option.
- Added font info to hOCR output.
- Enabled streaming input and output of multi-page documents.
- Many bug fixes.

2014-02-04 - V3.03(rc1)
- Added new training tool text2image to generate box/tif file
  pairs from text and truetype fonts.
- Added support for PDF output with searchable text.
- Removed entire IMAGE class and all code in image directory.
- Tesseract executable: support for output to stdout; limited
  support for one
  page images from stdin  (especially on Windows)
- Added Renderer to API to allow document-level processing and
  output of document formats, like hOCR, PDF.
- Major refactor of word-level recognition, beam search,
  eliminating dead code.
- Refactored classifier to make it easier to add new ones.
- Generalized feature extractor to allow feature extraction from
  greyscale.
- Improved sub/superscript treatment.
- Improved baseline fit.
- Added set_unicharset_properties to training tools.
- Many bug fixes.
- More training source data included.
