setting up starter materials for testtwf tokyo
Added a 10px vertical margin between the 2 div in the following 5 reftests:
src/backgrounds/background-color-029-ref.xht
src/backgrounds/background-color-093-ref.xht
src/colors/color-005-ref.xht
src/colors/color-006-ref.xht
src/colors/color-144-ref.xht

Created and added first-letter-selector-028-ref.xht
as a reftest for first-letter-selector-028.xht
Changed 50% to 40% in the following tests and
associated reftests (52 files total):
border-left/right/top/bottom-/outline-/color
(052-53,073-74,093-94,113-14) tests.

I removed the meta flags in reftests.

I reviewed+approved the tests and reftests ... albeit 1in could
be better replaced with 100px and
"(...) the boxes below are the same color"
could be replaced with the more consistent wording
"(...) there are 2 squares with the <strong>same color</strong>."
Submitting a few test cases for calc() in media queries
Fix metadata mistake
Created margin-backgrounds-003.xht to emphasize the fact that
margins are always transparent and through which we normally
would/should see the background-color (or background-image)
of its parent.
Created and submitting
border-image-017.xht
border-image-018.xht
border-image-019.xht
border-image-020.xht
border-image-slice-001.xht
border-image-slice-002.xht
border-image-slice-003.xht

Removing
background-clip-237.html
since it was already submitted under the filename
background-clip-010.html
