* gtkflist.[ch]: New files. This is a "file list" widget derived
from GtkCList that does several things:
- Overrides all mouse and keyboard event handlers.
- Implements its own, *sane* selection behavior, unlike
GtkCList's, which is broken.
- Implements the same selection behavior as the desktop,
which is a) correct, and b) consistent.
* gscreen.c (panel_create_file_list): Use the GtkFList widget.
(panel_widget_motion): Changed the drag thresholds to be the same
as in gtkdnd.c.
(start_drag): New convenience function to begin a drag operation.
(panel_widget_motion): Use start_drag().
(panel_clist_scrolling_is_desirable): Offsets must be with respect
to the clist_window, not to the allocation.
(panel_clist_drag_motion): Normalize the y coordinate of the
motion event to the clist_window.
* gdesktop.c (desktop_icon_info_destroy): Reset the
last_selected_icon to NULL if it is destroyed.
* Makefile.in: Added gtkflist to the list of files.
