### 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
