Use named cursors for the DND cursors, the names are "dnd-none",
"dnd-copy", "dnd-link", "dnd-move" and "dnd-ask". Also use an RGBA
cursor instead of cursor+window when possible. This saves
roundtrips during the drag operation, and makes translucent icons
possible.
* gtk/gtkdndcursors.h: New file, containing inlined pixbufs
for the default dnd cursors.
* gtk/gtkdnd.c (struct _GtkDragSourceInfo): Store the cursors
used during the drag here, also store the icon pixbuf here.
* gtk/gtkdnd.c (drag_cursors): Store the cursor names here. Also
switch the default cursors from xbm to inlined pixbufs.
* gtk/gtkdnd.c (gtk_drag_get_cursor): This function now takes the
GtkDragSourceInfo as well, since it has to composite the
drag-specific cursors. The cursors combined from the image of
the themed cursor and the icon_pixbuf stored in the info.
* gtk/gtkdnd.c (gtk_drag_begin_internal): Don't set the default
icon if there is an icon_pixbuf, which will be composited into
the cursor later.
* gtk/gtkdnd.c (set_icon_stock_pixbuf): If appropriate, store
the pixbuf in the info struct for later compositing into the
cursor instead of creating an icon window.
* gtk/gtkdnd.c (gtk_drag_drop_finished): If we used an
RGBA cursor for the drag, and need to display the cancel
animation, construct the icon window here.
* gtk/gtkdnd.c (gtk_drag_source_info_destroy): Unref the
drag-specific cursors and the icon_pixbuf when done with
the drag.
