+%
+% The intent of this package is to be a drop-in replacement for the already
+% existing CTAN package `ocgx' by Paul Gaborit, and also for `ocg-p' and `ocg'.
+%
+% It re-implements the functionality of the ocg, ocgx and ocg-p packages
+% and adds support for all known engines and backends including
+% latex+dvips+ps2pdf, xelatex, latex+dvipdfmx, lualatex.
+%
+% With ocgx2, PDF layers may extend across page breaks.
+%
+% ocgx2 implements OCMDs (optional content membership dictionaries)
+%
+% Adds some minor improvements, such as package options, remembering option.
+% settings of reopened ocgs, correct behaviour of ocg switching links that were
+% themselves placed on layers, compatibility with the animate and media9
+% packages.
+%
+% Re-implements hyperref's `ocgcolorlinks' option to produce coloured links
+% that may wrap around line breaks and page breaks.

+% Copyright notice: The code that follows until the end of the file was
+% taken in large parts from Paul Gaborit's `tikzlibraryocgx.code.tex' with
+% some additions/fixes:
+%
+% - opts={...} inside ocg={...} allows ocg-environment options to be passed
+% to a TikZ scope
+%
+% - The style ocmd={...} is another way for turning a TikZ scope into a PDF
+% layer (in addition to ocg={...}). It has two sub-keys, ref={...} and
+% visibility={...}, which have the same meaning as the optional and the
+% mandatory arguments of the `ocmd' environment
+%
+% - TikZ objects to be turned into OCG switching links accept the additional
+% key
+%
+% trigger ocg = onmousenter | onmouseexit | onmousedown | onmouseup |
+% onmouseall
+%
+% to react to various mouse gestures
+%
+% - switching links properly sized and working in scaled tikzpictures
