+### HOWTO ###
+# Add a rendering test: 
+#  - create the svg file
+#  - inkscape <yourfile>.svg -d 96  -e expected_rendering/<yourfile>.png
+#  - inkscape <yourfile>.svg -d 384 -e expected_rendering/<yourfile>-large.png
+#  - add the test in the list below
+#  - use stable if possible to generate the reference png files
+#  - git add <yourfile>.svg expected_rendering/<yourfile>-large.png expected_rendering/<yourfile>.png
+#  
+# Fix a failing test (due to a change in code):
+#  - DO *NOT* MODIFY the expected rendering (or the svg) before getting advice from inkscape-devel@
+#  - fix your code if possible
+#  - IF you change introduces a greater compatibility with css or browsers
+#  - AND you cannot reasonably "update" files from older versions to match the appearance
+#  - AND inkscape-devel@ has a consensus that it's the only way
+#  -> do as you must
+#  - manually double check the changes
+# Fix a failing test (due to a change in pixman or cairo):
+#  - update renderings. Use a *stable* version to generate the renderings, NOT TRUNK
+#  - manually check appearances
