About font default values: The default font is chosen by the interfaces depending on the context.

For example, there can be a different default font for a button and a groupbox.

The loading routine automatically recognizes the format, so it is also used to load the images from Delphi form streams (e.g. .dfm files).
When the handle is created, it is up to the interface (gtk, win32, ...) to convert it automatically to the best internal format. That is why the Handle is interface dependent.
