* NEW: More snippets for declaring local variables: "di" declares an integer variable, "ds" a string variable... [GB.IMAGE] * NEW: Image.FillRect() ignores transparency. But a new Image.DrawRect() method takes it into account now. [GB.QT4] * BUG: Mouse event properties are enabled now during a double click event handler. [GB.WEB] * NEW: HTTP compression is automatically enabled if the response is buffered, and if the HTTP client can handle it of course. git-svn-id: svn://localhost/gambas/trunk@3128 867c0c6c-44f3-4631-809d-bfa615b0a4ec
