Implemented ultra-cool layout for the events that share the same time
1998-05-18 Miguel de Icaza <miguel@nuclecu.unam.mx> * gncal-full-day.c (layout_children): Implemented ultra-cool layout for the events that share the same time range. Gals and guys you can now drop Outlook on the recycle bin. Which reminds me. We do not have a recycle bin. How could that happen in a project as cool as this one? Someone explain this to me. 1998-05-18 Federico Mena <federico@nuclecu.unam.mx> * gncal-full-day.c (paint_back): Eliminated unnecessary border repainting. svn path=/trunk/; revision=218
