2001-06-03  Havoc Pennington  <hp@pobox.com>

	* gtk/gtkstyle.c (gtk_default_draw_slider): make this special-case
	hscale/vscale details, so we can use it for scrollbar as well.

	* tests/testgtk.c (reformat_value): honor digits from GtkScale

	* gtk/gtkenums.h (GtkTroughType): Remove this enum
	(GtkScrollType): add START and END from GtkTroughType

	* gtk/gtkstyle.c (gtk_default_draw_slider): was not properly using
	its x/y arguments

	* gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkscrollbar.h,
	gtk/gtkscrollbar.c, gtk/gtkscale.h, gtk/gtkscale.c,
	gtk/gtkhscrollbar.h, gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.h,
	gtk/gtkvscrollbar.c, gtk/gtkhscale.h, gtk/gtkhscale.c,
	gtk/gtkvscale.h, gtk/gtkvscale.c: Rewrite GtkRange and subclasses.

	Notable changes in the process:

	- stepper_size style property is the height for vertical
	  ranges, width for horizontal; the other dimension matches
	  the trough size
	- add ability to do NeXT-style steppers (and several other styles
	  that don't make any sense)
	- added min_slider_length, fixed_slider_length properties to
          GtkScrollbar
        - cleaned some private (or at least useless) functions out of
          gtkscale.h
        - moved bindings to GtkScale from subclasses, even arrow keys,
	  since blind users don't know scale orientation.
        - change move_slider action signal to use new GtkScrollType,
	  remove GtkTroughType argument
	- digits rounds the values a range will input to the given
	  number of decimals, but will not try to force adjustment
	  values set by other controllers. That is, we no longer
	  modify adjustment->value inside a value_changed handler.
	- added getters for GtkScale setters
        - middle-click begins a slider drag
