Change things around so that warp-to-click and jump-by-pages are
bound to left-click and shift-left-click, depending on the value
of gtk-primary-button-warps-slider. Autoscrolling is bound to
right-click.
To achieve this, reorganize gtk_range_multipress_gesture_pressed
so that the functions are clearly separated.
Make shift right-click on the trough start autoscrolling. The
autoscrolling is similar to the way steppers operate now, with
the difference that we vary the scrolling speed based on the
distance of the pointer from the widget.
Clicking on steppers does different things depending on which
button you use. We used to scroll to the end on secondary click
and use high-speed autoscrolling on middle-click. Switch these
two around, since the scroll-to-end functionality is less likely
to be useful, and the seconary button makes the autoscrolling
more easily available.
The calculation to update the initial slider position on zoom
changes was not working correctly when using keys to toggle
zoom on and off for scales. Avoid it by updating the position
beforehand.
Moving the mouse while pressing one of the steppers was making
the slider jump to the end, unexpectedly. This was caused by the
drag gesture kicking in when it shouldn't. Fix this by making
all drag gesture signal handlers only do something if we are in
a drag thats started on the slider.

The direction in which the slider moves can be inverted by setting the
inverted property. But the draw method does not check this, instead it
checks if the direction of the widget is set to be right to left.
Call the should_invert function in order to determine if the direction
of the range should be inverted. It too checks the widget's direction,
but also checks the "inverted" property, and allows the range to be
drawn inverted even if it is vertically oriented.

Compute the proportion of the range that should be filled to match the
fill level, and use it to compute the starting point and length of the
area between the slider and the fill level.

As Sebastian pointed out, just resetting the initial slider
position was an incomplete fix, because it does not cause the
delta to be recomputed, which is important in this scenario,
because you've likely travelled some distance over the slider
before the long press kicks in.
Instead, explicitly record both the slider position and the
delta.
We record the starting position on button press, but only
start the zoom mode when the long press timeout kicks in.
Depending on circumstances, this can cause a noticable jump.
Avoid this by resetting the recorded starting position after
the long press timeout. Suggested by Sebastian Keller.
The adjustment value being equal is checked by
gtk_adjustment_set_value() and the necessity of calc_layout() is handled
by the value_changed signal handler.
Css margin now works on the slider as they do on the trough.
The margin is not considered in the space allocation as it is for
the trough, so the slider width will be the set slider-width -
margins. Spefifying margins on the main widget in the css will
clearly affect both the trough and the slider, so theme changes are
needed.
This will be used to identify a scrollbar is being dragged - we
don't actually need the style class; another way to keep track
of the dragging status would be ok too.
The scale in the selectable listbox in page 2 of gtk3-widget-factory
has the flaw that the row is getting selected even when one only
interacts with the scale - unlike e.g. the checkbutton and button
further down in the listbox.
The problem is that GtkRange is trying to claim the sequence for
the drag gesture from the ::pressed handler of a multipress
gesture. Since the drag gesture hasn't seen the sequence at this
point, that is ineffective.
The fix here is to rearrange the gestures so that the multipress
gesture sees the sequence before the drag gesture, and then
claim the sequence from the ::drag-begin handler.
This is a temporary workaround for scrolling units being amplified
on quartz, due to the assumption that smooth scrolling deltas are
always in some abstract unit similar to the one from xi2.
A proper solution for the situation is described in bug #736121, but
since we are close to release, this patch solves the issue temporarily.

... in places where we draw a background. This was changed for GTK 3.0.0
to allow animations, but these days it doesn't make sense anymore to use
gtk_render_activity() for backgrounds.
