Text: interface for font converters.

Provides a way to convert font into different format (either with or
without contents of associated glyph cache) or import/export glyph cache
(i.e. to avoid recreating it from scratch every time).

@brief Base for font converter plugins
Provides functionality for converting arbitrary font to different format.
@section AbstractFontConverter-subclassing Subclassing
Plugin implements doFeatures() and one or more of `exportTo*()` / `importFrom*()`
functions based on what features are supported.
You don't need to do most of the redundant sanity checks, these things are
checked by the implementation:
- Functions `doExportFontTo*()` are called only if @ref Feature "Feature::ExportFont"
is supported, functions `doExportGlyphCacheTo*()` are called only if
@ref Feature "Feature::ExportGlyphCache" is supported.
- Functions `doImportGlyphCacheFrom*()` are called only if
@ref Feature "Feature::ImportGlyphCache" is supported.
- Functions `doExport*To*Data()` and `doImport*From*Data()` are called only
if @ref Feature "Feature::ConvertData" is supported.
- Function `doImport*FromData()` is called only if there is at least one data
array passed.
