Respect CSS border-image-width.
Properly support gradients as a border-image-source.
Only emit a border item if the border-width is non-zero
for simple borders but still emit one if the item is
an image as paint worklet that are not drawn cause servo
to hang and fail tests.
Add a new test and mark 4 more as passing.
Use the color clip corresponding to the last background-image instead
of the last background-clip. (There may be more clips than images and
clips are repeated if there are less clips than images.)
Add a test.
Add an automatic test for border-image-outset with a gradient.
Convert two tests from UTF-8 LE with CRLF line endings to
UTF-8 with LF endings as the old files could not be viewed with servo.
