= Notes on the collapsing border model =

Painting the borders for the separate border model is relatively simple. For 
the collapsing border model this can become complicated. The following is an 
attempt to analyze how the borders should be painted in this model. The 
sequence of images should also help identify what information besides the 
traits defined in the XSL-FO spec are necessary to properly paint the 
individual borders.

 1. A part of a table (grid lines)

 2. Resolution of the individual borders according to the rules in the FO spec

 3. Inner and outer join points (where the individual borders meet)

 4. Resulting borders
