Another small command line application that loads an example file that references entities not present

in the file, and provides these entities with matching styles dynamically in the `SvgDocument.Open` call.

----------
|

This is a simple command-line application to convert one or many input SVG files to PNG images. It shows how to open a SVG document and create bitmap, and how to save resulting bitmap to a PNG file.
