The new tests for vertical align with vertical writing mode

Gérard,

I've submitted the new tests for 'vertical-align' property with vertical
writing-mode.
https://hg.csswg.org/test/rev/8dd028e99e73
Could you review it?


First, I've created the four test-cases for the pattern which is not
affected by its baseline.

writing-mode: (vertical-rl)
x
vertical-align: (top | text-top | text-bottom | bottom)
=> four pattern.

I think that in these test it is no need to test with variation of
text-orientation because the calculation with 'top', 'text-top',
'text-bottom' and 'bottom' is not affected by baseline.

I will create test other properties which is affected by its baseline
('middle', 'sub', 'super', <percentage>, <length>) after the above test
case is approved.


Hajime.
