* src/pcfdriver.c: fixed incorrect bitmap width computation

Browse Source 
* docs/docmaker.py: updated the DocMaker script in order to add
    command line options (--output,--prefix,--title), fix the erroneous
    line numbers reported during errors and warnings, and other formatting
    issues..

    * src/base/ftcalc.c: various tiny fixes related to rounding in 64-bits
    routines and pseudo"optimisations" :-)
