* Added win32_desktop.cpp/.h defining a method Win32Desktop::GetWorkArea.
Added code to wWinMain in main.cpp to position the window relative to the work area, which may not be at (0, 0) depending on the user's configuration.
* Corrected the constraint on the size value calculated by main.cpp.
* Fixed references to min to use std::min.
* Reworked GetWorkArea in win32_desktop.cpp to treat the supplied origin and size as containing an existing window rectangle, and to find the monitor that contains or is closest to that window.
Added function FitToWorkArea to win32_desktop.cpp/.h.
Updated main.cpp to use Win32Desktop::FitToWorkArea instead of explicitly constraining the size.
