Configure fonts

When EPPlus renders text to an image-based format it needs to measure and shape the text using real font data. This applies to the HTML/SVG and PDF exports. EPPlus ships with sensible defaults and a built-in fallback chain, so in most cases you don't need to configure anything — but when you do, Workbook.ConfigureFonts lets you control where fonts are loaded from and how missing fonts and glyphs are handled.
