Problem

The reference documentation for theFontManager class says that there is a singleton:

This module provides a singleFontManager instance that can be shared across backends and platforms.

However, it doesn't mention that this singleton is namedfontManager.

Suggested improvement

• The docstring should clarify that the singleton is namedfontManager, rather than implying that theFontManager class is a singleton:

  This module provides a single `FontManager` instance, `fontManager`, that is shared across backends and platforms.

• ThefontManager instance should be documented as a global variable:

  ..data::fontManager    The singleton instance of:class:`FontManager`
