ea786e25a4 api/baseapi: Fix memory leaks at program termination
Calling TessBaseAPI::Clear() which calls TessBaseAPI::ClearResults()
which calls SavePixForCrash(0, NULL) is needed to release objects
allocated in global_crash_pixes.

caffb3133b Remove unneeded 'struct' from TessBaseAPI::GetHOCRText (issue #414)
It conflicts with a previous 'class' declaration for ETEXT_DESC:

include/tesseract/baseapi.h:594:21:
 Struct 'ETEXT_DESC' was previously declared as a class

ea401c9046 Only generate dir for HOCR when needed - fixes #208
Takes advantage of inheritance and dir="ltr" default to:
 - only generate paragraph dirs which are not ltr
 - only generate word dirs which don't match enclosing paragraph

Tested against LTR, RTL, and mixed direction files. Files for the
latter two cases are in a separate commit on the ltr-test-files branch.

431786276c INCOMPATIBLE fix to hOCR line height information - fixes #225.
This fixes the duplicate line IDs caused by inserting height information
into the middle of the ID and it moves the line height info into
the title attribute like everything else, rather than using non-standard
HTML attributes (which won't validate).

This change may break consumers of the HTML output, but 3.04 has only
been in the wild for 6 months and the current HTML is invalid, so I 
believe the benefit outweighs the cost for the fix.

53fc4456cc Fixed issue 1252: Refactored LearnBlob and its call hierarchy to make it a member of Classify.
Eliminated the flexfx scheme for calling global feature extractor functions
through an array of function pointers.
Deleted dead code I found as a by-product.
This CL does not change BlobToTrainingSample or ExtractFeatures to be full
members of Classify (the eventual goal) as that would make it even bigger,
since there are a lot of callers to these functions.
When ExtractFeatures and BlobToTrainingSample are members of Classify they
will be able to access control parameters in Classify, which will greatly
simplify developing variations to the feature extraction process.
