replaced the QMask radio buttons ba a single check button. Still needs

2001-11-29  Michael Natterer  <mitch@gimp.org>

	* app/display/gimpdisplayshell.[ch]: replaced the QMask radio
	buttons ba a single check button. Still needs some tuning.

	* app/display/gimpdisplayshell-handlers.c
	* app/display/gimpdisplayshell-qmask.[ch]: changed accordingly.

	* app/tools/gimptool.[ch]: added "gboolean handle_empty_image" to
	the GimpTool structure.

	* app/tools/gimpmovetool.c: set it to TRUE.

	* app/tools/gimpfuzzyselecttool.c: don't gimp_[set|unset]_busy()
	while calculating the selection but set the busy cursor on the
	display manually (we have the pointer grabbed anyway).

	* app/display/gimpdisplayshell-callbacks.c: don't check for
	GIMP_IS_MODE_TOOL(active_tool) but look at
	active_tool->handle_empty_image. Removed the checks for
	GIMP_IS_FUZZY_SELECT_TOOL(active_tool) because fuzzy_select
	doesn't set GIMP busy while it's active any more.

	* app/tools/transform_options.[ch]
	* app/tools/gimptransformtool.c
	* app/tools/gimprotatetool.c
	* app/tools/gimpscaletool.c: added widgets for the transform tools'
	constraints (one more #51108 issue fixed).

	* app/tools/gimperasertool.c: cosmetic.

	* app/widgets/gimpdockbook.c: don't hardcode GtkNotebook's
	tab_border to 0 but add a style property for it...

	* themes/Default/gtkrc: ...and set it to 0 here.
