* BUG: Correctly update the code editor menu when the project is running. [GB.FORM.MDI] * NEW: The Workspace.ButtonPosition property has been removed. * NEW: The Workspace tabstrip now uses embedded close buttons. [GB.IMAGE] * NEW: The Image.Gray() method has been renamed as Image.Desaturate(). * NEW: The Image.Transparent() method has been renamed as Image.Erase(). [GB.IMAGE.EFFECT] * NEW: The Image.Gray() and Image.Desaturate() methods have been removed. git-svn-id: svn://localhost/gambas/trunk@3105 867c0c6c-44f3-4631-809d-bfa615b0a4ec
