ISSUE-189: do regions scroll their flowed content? [DFXP 1.0]

TTML 1.0 is silent about the presentation processor behavior when text is flowed into a region and exceeds the region boundary due to <br>. One might infer from the silence and the clipping discussion that scrolling does not occur. However, the SDP-US Example 5 implies that regions scroll - the region is named "rollup" and the body text says "this could go on all day".  If regions do not in fact scroll, then a "roll-up" example would need to be constructed very differently.

TTML 1.0 region behavior needs to be clarified when the flowed text exceeds the region boundary; and depending on the answer, the SDP-US Example 5 corrected.
