More info for the documentation

Maybe this will help somebody.  I just spent the last day trying to resolve all the dependencies needed for a Linux Docker image.  Here's what I came up with
{code:java}
FROM openjdk:8-jre-alpine
RUN apk add --no-cache tesseract-ocr python3 py3-numpy imagemagick python3-tkinter && \
  pip3 --no-cache-dir install --upgrade pip setuptools wheel && \
  apk add --no-cache --virtual .build-deps gcc g++ zlib-dev make python3-dev py-numpy-dev jpeg-dev gfortran lapack-dev && \
  pip3 --no-cache-dir install scikit-image && \
  apk del --no-cache .build-deps
{code}
 

Also, this is the test that Tika does internally to ensure that all the dependencies are there

 python3 -c "import numpy, matplotlib, skimage, _tkinter;"

If you don't get any errors, then you're good

> When I tried to work with rotation.py, I found that we should allow python to be python3 (not require an alias), and I found that rms_flat (once deprecated) has actually been removed in recent versions of matplotlib.
