Documetation points to some nonexistent marble diagrams

[Stephan202]

Noticed this while reading some JavaDoc in the context of a 1.2.6 -> 2.0.5 upgrade. I wrote the following script to list all JavaDoc-referenced PNGs which do not yield an HTTP 200 response when resolved:

#!/usr/bin/env bash

find . -name '*.java' -print0 \
  | xargs -0 grep '^\s*\*' \
  | grep -oP 'https.*?\.png' \
  | sort -u \
  | while read -r I; do
      curl -L -o /dev/null -s -w "%{http_code} ${I}\n" "${I}"
    done \
  | grep -v '^200'

And then applied it to the 2.x branch (rev 0a2610e). The output is:

Note that the images inside the javadoc may be skewed. Let me know if you'd like to post a PR that fixes the width= and height= constants for these.

[Stephan202]

@akarnokd, thanks for generating these images. As for your fixing the dimensions, I filed PR #5087 for that; let me know whether that's what you intended.
