RackElevationSVG falls back to RACK_ELEVATION_DEFAULT_* config
parameters, which raise AttributeError on the target NetBox version.
Pass the dimensions explicitly instead.
Add a Pillow-based PNG rack renderer (role colors, unit legend,
full-depth devices shown dimmed from the other side). It is used for
Word when cairosvg is unavailable and replaces a failed SVG in all
formats.
