[vtkusers] VTK compiling error with MinGW-w64: "cast loses precision"

[Chaffra Affouda]

Hi Nirhal,

  I had a similar error but this should have been fixed in the trunk. 
line 2348 should read

if (!this->GetGlyphIndex(reinterpret_cast<size_t>(scaler->face_id), c,
                            &gindex))

If not you need to pull from the trunk.
