Version 3.0 Patchlevel 3 Added Features/Bug Fixes

1. Fix bugs with change font properties of transformed text. Thanks to Kyle Bateman <kyle@actarg.com> for pointing out the problems.

2. Getting rid of uncessary redraws on transformed text when scrolling.

3. Make CenterAnEndPoint() work for rotated polyline objects.

4. Add a new internal command: rotate_selected_obj(<degrees_to_rotate>). With this command, the following code will keep rotating an object named "toy" forever (until <ESC> is entered):

           exec=disable_undo();
                begin_animate();
                select_obj_by_name(toy);
                while(1,do_it);
                unselect_all_obj();
                end_animate();
                enable_undo();
   
           do_it=rotate_selected_obj(10);
