Flowtext and Orientation

Hi, folks-

The 1.2 draft mentions how vertically-oriented text is handled, but it
doesn't address text on an angle other than 0 or 90 degrees. Also, there is
the issue of mixed orientation, such as a 'flowSpan' with vertical
orientation emebedded in a 'flowPara' with horizontal orientation. This is a
practical consideration, since Japanese documents often have mixed
orientations depending on the writing system they are using for a section of
text. Will a strip be laid out for this text, or is mixed orientation not
allowed?

Also, I think that there should be a way to explicitly set line-height. Say,
for example, a 'line-height' attribute. It might be the case that the author
deliberately wants to overlap lines of text/images.
