Test project and prebuild exe file.

Run WindowsProject1\x64\Release\WindowsProject1.exe from zip archive and test
rbutton on colored regions. Red is first child (low level) blue is last child
(top level). Message box will shows wParam result. In recent Windows it always
points to first child or parent. First click emulated by sending WM_RBUTTONDOWN
message with middle of top level (blue area) window coordinates.
