* widgets/e-canvas-utils.c, widgets/e-canvas-utils.h: e_canvas_item_move_absolute is just a helper function not supplied by the gnome_canvas.[ch] I put it here so that multiple items can use it. * widgets/e-reflow.c, widgets/e-reflow.h: This item contains a number of other items and places them into multiple columns. The items contained must support a number of arguments and signals to allow the reflow to interact with them. * widgets/test-reflow.c: This is a test program for e-reflow. * widgets/e-text.c, widgets/e-text.h: Added properly drawn selected text. Added some preliminary code for X selection handling and cut & paste. * widgets/e-minicard.c, widgets/e-minicard.h: Added ARG_HAS_FOCUS handling. Made label display random for more interesting tests of multiple cards. Tweaked sizing information for better display. * widgets/e-minicard-label.c, widgets/e-minicard-label.h: Added ARG_HAS_FOCUS handling. * widgets/Makefile.am: Added the reflow test and reflow files. svn path=/trunk/; revision=1566
