Version 3.0 Patchlevel 4 Added Features/Bug Fixes

1. Fix some minor bugs with clicking in the panel window.

2. Fix a bug with redrawing transformed text objects.

3. Add two new internal commands: call_simple_shortcut(<shortcut_name>) and call_one_arg_shortcut(<shortcut_name>,<arg>). With these commands, the following code will make a pixmap object named "toy" gray:

           exec=disable_undo();
                begin_animate();
                select_obj_by_name(toy);
                call_simple_shortcut(MakeGray);
                unselect_all_obj();
                end_animate();
                enable_undo();
