[switch]: How does the switch behave in different writing modes?

[gfellerph]

How should the following table be completed for the last column in vertical and sideways writing modes?

Writing mode	Direction	"on" position
horizontal-tb	ltr	right
horizontal-tb	rtl	left
vertical-rl	ltr
vertical-rl	rtl
vertical-lr	ltr
vertical-lr	rtl
sideways-rl	ltr
sideways-rl	rtl
sideways-lr	ltr
sideways-lr	rtl

See #1098 for a resolution on the horizontal writing mode.
