An ink section is treated as a seperate special paragraph and is laid out accordingly during the display. If the window is not wide enough to accommodate the ink region then it is just truncated. There is no flow behavior of any kind. Ink windows should be displayed with a solid line border around them. The contents of the tag must be a series of points in parenthesis.
Interactive capabilities Selecting an ink window puts it into edit mode.
When the window is in edit mode it has a handle on the lower right corner that the user can drag to resize the window. Once a stroke is created it is the selected stroke and should be highlighted as such.
