+Subject: [PATCH] Switch graphviz files to use HTML-style labels
+
+With recent versions of graphviz, generation of the diagrams in the documentation
+fails with:
+
+ /usr/bin/dot -Tpng -oxml/x-architecture.png dot/x-architecture.gv
+ Warning: flat edge between adjacent nodes one of which has a record shape - replace records with HTML-like labels
+   Edge xserver -> comp
+ Error: getsplinepoints: no spline points available for edge (xserver,comp)
+ Error: lost xserver comp edge
+ Error: lost xserver comp edge
+ Error: lost comp xserver edge
+ Error: lost comp xserver edge
+
+http://www.graphviz.org/content/i-havent-been-able-render-these-files-graphviz-226 indicates
+that the error message basically means that the authors of graphviz consider record-style
+labels to be deprecated and are no longer fixing errors with them. This patch changes
+the labels to be in the HTML style, which seems to require duplicating style between all
+the nodes, but it's not like these files are often edited.
+
+The result is not exactly the same but is quite similar.
