# Above is the imagemagick command to render an svg to png. Unfortunately, its support for SVGs
# with CSS isn't very good (with rsvg and even moreso the built in renderer) so we use cairosvg.
# This can be installed with:
# pip install cairosvg==1.0.22 # Version 2 doesn't support python 2
# pip install tinycss
# pip install cssselect # These are necessary for CSS support
# You'll also need xmlstarlet from your favourite package manager
#
# Cairosvg doesn't suport rendering at a specific size (https://github.com/Kozea/CairoSVG/issues/83#issuecomment-215720176)
# so we have to 'resize the svg' first (add width and height attributes to the svg element) to make it render at the
# size we need.
# XXX: This will break if the svg already has width and height attributes
