/* Pango/Font Explorer
*
* This example demonstrates support for OpenType font features with
* Pango attributes. The attributes can be used manually or via Pango
* markup.
*
* It can also be used to explore available features in OpenType fonts
* and their effect.
*
* If the selected font supports OpenType font variations, then the
* axes are also offered for customization.
