  Hash : a9b96d0d
  Message : Include windows.h from one place to ensure that min and max macros are not defined. These conflict with the STL functions of the same name. This is to make the standalone ANGLE gyp build work again. Review URL: https://codereview.appspot.com/7211043 Also includes r1729 which adds the missing new file. git-svn-id: https://angleproject.googlecode.com/svn/branches/dx11proto@1790 736b8ea6-26fd-11df-bfd4-992fa37f6226
