034d666e7a Replace use of TLOG_FATAL() with tprintf() and exit(1) (#349) 
Asserts should not be used for missing or invalid input in the command
line! This leads to a bad UX.

76ed9decb3 Only enable extra ligatures with recent Pango versions 
Pango's opentype feature selection functions are only available
from version 1.38+, which is still quite new, so ensure it's just
ignored if using an older version.

9100adcbde Enable all ligatures available in a font for text2image rendering 
This enables all OpenType ligatures for a specific font, where
available. Specifically, it explicitly enables the OpenType
features liga (standard ligatures), hlig (historical ligatures),
clig (contextual ligatures), and dlig (discretionary ligatures).

This feature requires Pango 1.38 or newer.

306610c5ec Use shell quoting rather than pluses to separate font arguments in tesstrain.sh 
The way tesstrain.sh handled font names was really weird, using '+'
signs as a delimiter. However quoting arguments is a much more
straightforward, standard and sensible way to do things.

So whereas previously one would have used this:
  --fontlist Times New Roman + Arial Black
Now they should be specified like this:
  --fontlist "Times New Roman" "Arial Black"

Unicharset extractor problems with wchar

379da1f2e0 training/unicharset_extractor.cpp: Print whether WCTYPE is included 
Character properties are autogenerated only if wctype is found on the
system.  However, it is not possible to know if a version of
unicharset_extractor was compiled with this support (especially if it
was installed as a pre-compiled binary).

This commit adds a print to the usage details to output if the binary
was compiled with wctype support.

de789ac8ea Use mktemp to create workspace directory 
mktemp is a better idea for security, as well as enabling users to
specify a different directory using the TMPDIR environment variable,
which is useful if /tmp is a small tmpfs.

Also fix a bug where the first few log messages were failing as the
workspace directory wasn't been created early enough.

c0133ecfa6 Add --exposures option to tesstrain.sh 
This flag can be used to specify multiple different exposure levels
for a training. There was some code already in tesstrain_utils.sh
to deal with multiple exposure levels, so it looks like this
functionality was always intended.

The default usage does not change, with exposure level 0 being the
only one used if --exposures is not used.

8e71c79dc2 Remove --bin_dir option from tesstrain.sh (should use $PATH instead) 
The --bin_dir option to tesstrain.sh is not useful, as $PATH does the
same job much better, so switch to relying on that instead.

This also makes the code a bit more readable, as it removes the need
to refer to binaries as COMMAND_NAME_EXE rather than just command_name.

e110b14465 tesstrain.sh: Initialise fontconfig even if Arial isn't available 
The fontconfig initialisation hardcodes using Arial. However it may
not be available, whereas the fonts being used later will be, so use
one of them for initialisation instead.

422c424995 tesstrain.sh: Only set FONTS if they weren't set on the command line 
Previously the fonts specified in language-selection.sh would override
any specified on the command line.

This changes language-specific.sh from overriding a user request to
just setting the default fonts if none are specified with --fontlist.

8d0f59d09d tesstrain.sh: Only fall back to default Latin fonts if none were provided 
The --fontlist argument to tesstrain.sh was always ignored, even if
the language had no specific fonts specified in language-specific.sh.

Change this behaviour so the --fontlist argument is used if no specifc
fonts are selected by language-specific.sh.
