Subject: [PATCH] fix hang on windows in pixel_cast

  - manifested converting double -> int64_t.
  - it is unclear why this explicitness is needed on windows
    to avoid greater calling itself. But it is clear that the
    static_cast<double>(<std::int64_t>) is not enough for the
    template deduction to match the <double,double> case automatically
  - Making this explicit is probably better anyway, but odd it is needed.
  - Finishes closing #2893, refs #2893, amends 96f7120ecc11 and d29a0f18b1fb9c
  - Seen with both VS 2014 CTP 4 and VS 2015 Preview
