Add some test options to test/editor.cxx.
These options are not enabled by default, but you can enable them by defining macro DEV_TEST. This adds buttons to toggle wrap mode, scrollbar positions, and to increase or decrease the window size (width). Note: this can be used to test STR #3272 and the fixes in a follow-up commit. Note: same changes as r11204 in branch-1.3. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11207 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
