Fixes warnings like 'conversion' conversion from 'type1' to 'type2', possible loss of data
DecimalPoint is a char type instead of Integer, see Units_UnitsDictionary.cxx
In OSD_WNT_1.cxx, clamped dialog size instead of direct casting which could result in loss of data (i.e. wrong dialog size).
In GeomTools, adjusted int to std::streamsize
Changed some of the interface types (inc files) to correct some implicit casts.
