  Message : Made the API of shader translator library consistent. - We recently started using OpenGL-type enums. This CL makes all old enums consistent with the new scheme. - Renamed TBuiltInResource to ShBuiltInResources to have a consistent prefix BUG=46 Review URL: http://codereview.appspot.com/2328041 git-svn-id: https://angleproject.googlecode.com/svn/trunk@443 736b8ea6-26fd-11df-bfd4-992fa37f6226
