libwps/libwps.msvc.warnings.patch

fix MSVC warnings:

* various C4946 reinterpret_cast between related classes
* silly C4305 truncation from double to float
* C4806: no value of type 'bool' promoted to type 'int'
  can equal the given constant (real bug?)
* C4701: pot. uninitialized variable 'ucs4Character'
