* BUG: Compile files with maximum optimization correctly. [DEVELOPMENT ENVIRONMENT] * BUG: Remove The Form_Close event handler in the FHelp form. It did stupid things indirectly. [WIKI CGI SCRIPT] * NEW: Enhancements to support 2.0 and 3.0 descriptions on the same page. [GB.FORM] * NEW: Enhance the ColorChooser control. [GB.FORM.MDI] * BUG: Fix the Toolbar layout algorithm. [GB.IMAGE] * BUG: Image.Colorize() works again. [GB.IMAGE.EFFECT] * NEW: This component includes image filtering and effect routines. This is the old gb.image component from Gambas 2. Everything is not working correctly at the moment. [GB.QT4] * NEW: Color.LightForeground returns the light foreground color used for drawing separators and plain panel borders. * BUG: Prevent crashes coming from the fact that Qt deletes child widgets before emiting the destroy signal on the parent. git-svn-id: svn://localhost/gambas/trunk@2296 867c0c6c-44f3-4631-809d-bfa615b0a4ec
