This integration is minimum as discussed, in particular it does not feature any fltk cairo drawing substitution as in fltk2. Still it provides all the fundations to go further even in next 1.4 ... By default *no* cairo features are implemented nor linked, it can only be activated by --enable-cairo whose default is false. Please visit the README.cairo for complete description. + fixed UTF8 compilation pb on linux ubuntu + minor comments fixes on the fly git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6350 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
