A font chooser dialog shows installed fonts.
The dialog is non-modal with its owning dialog,
which is usually a plugin procedure's dialog.
When a user selects a font,
the dialog calls back but the dialog remains open.
The chosen font is only a choice for the owning widget
and does not select the font for the context.
The user can close but not cancel the dialog.
The owning dialog can close the font chooser dialog
when the user closes or cancels the owning dialog.
