This class is only here for backward compatibility;
all functionality is now in VariablePanel. Its orientation can now
be changed dynamically.
A View to separate its subviews vertically by a movable bar;
the size-ratios of the subviews can be changed by moving this bar.
The bar-handle is either an exposed knob (style == #motif)
or the forms defined in Scroller (style ~~ #motif)
or nothing.
The subvies dimensions MUST be given as relative sizes;
typically creation is done as:
p := VariableVerticalPanel in:superView.
v1 := <someViewClass> origin:0.0 @ 0.0
corner:1.0 @ 0.5
in:p.
v2 := <someViewClass> origin:0.0 @ 0.5
corner:1.0 @ 0.8
in:p.
v3 := <someViewClass> origin:0.0 @ 0.8
corner:1.0 @ 1.0
in:p.

VariableVerticalPanel is simply setting its orientation
to #vertical. See more examples there.
example:
|top p v1 v2 v3|
top := StandardSystemView new.
top extent:300@300.
p := VariableVerticalPanel
origin:0.0 @ 0.0
corner:1.0 @ 1.0
in:top.
v1 := View origin:0.0@0.0 corner:1.0@(1/3) in:p.
v2 := View origin:0.0@(1/3) corner:1.0@(2/3) in:p.
v3 := View origin:0.0@(2/3) corner:1.0@1.0 in:p.
v1 viewBackground:(Color red).
v2 viewBackground:(Color green).
v3 viewBackground:(Color yellow).
