When setting only SVG width, don't set height and vice versa

Fixed viewBox attribute parsing warnings

The problem was introduced in v2.2.0.

Added options, SVG size, graph fit & scale and return of existing renderer instance

• If a graphviz renderer instance already exists on an element, return the existing instance instead of creating a new one every time.
• Options can be set when the graphviz renderer is created
• Options can be set with the graphviz.options method
• Added options to set SVG width and height and to fit the graph to the resized SVG
• Added option to scale the graph within the SVG

Support drawing all node shapes through the draw API

This release introduces a breaking change of the Draw API. The rest of the API is backwards compatible.

• Added support for drawing all node shapes (except user-defined nodes) through the draw API.

NOTE: If the drawNode() method is going to be used, when loading the viz.js script, the script type shall be "application/javascript" or "text/javascript", e.g.:
<script src="https://unpkg.com/viz.js@1.8.0/viz.js" type="application/javascript/"></script>
If the drawNode() method is not going to be used, start-up time may be reduced by using the script type "javascript/worker", e.g.:
<script src="https://unpkg.com/viz.js@1.8.0/viz.js" type="javascript/worker"></script>

Fix "Unexpected value false parsing transform attribute."

• Fixed "Unexpected value false parsing transform attribute." error message. Probably harmless, but nevertheless...

Handle shapes with path elements

• Fixed growing edges from shapes containing path elements, e.g. the cylinder shape
• Fixed shape tweening to and from shapes with path elements, e.g. the cylinder shape
