Avoid 1) floating point division by 127, 2) conversion of bias to double, 3) FP addition, in favour of 1) integer multiplication by 127, and 2) integer addition. (Also costs extra work in the serialisation/deserialisation of the scale values, and conversion of weights to int formats, but these are all one offs). |

To run the tests, do the following in tesseract folder
autoreconf -fiv
git submodule update --init
export TESSDATA_PREFIX=/prefix/to/path/to/tessdata
make check
