[css-writing-modes] test results available

i have just posted an initial set of *simple* tests for writing-mode 
support at
http://www.w3.org/International/tests/repo/results/writing-mode-vertical
with results for major browsers. (See csswg-test on github for more 
detailed tests.)

it so far covers basic scenarios for vertical-rl and vertical-lr values.

the results include Microsoft Edge, and there are tests for prefixed and 
non-released versions as well as for the standard CSS syntax.

i was surprised to find that Edge supports writing-mode:vertical-rl/lr 
in addition to the old tb-lr/rl values.  With the imminent release of 
support in Firefox, this is good news (although Edge still doesn't have 
support for vertically oriented forms).
