    <thetext>Since 263084@main `FontCustomPlatformData` takes `FontPlatformData::CreationData` instead of `FragmentedSharedBuffer`.
The buffer is now a reference counted field of `FontPlatformData::CreationData` struct and will be automatically dereferenced when `FontCustomPlatformData` is destroyed.
It is an error to manually dereference it using Cairo font destroy function.</thetext>
