Make it possible to change the default font

[cbeust]

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

It's currently not possible to change the default font besides loading your own .ttf file.

It looks like all that's needed is to make Source public:

https://docs.rs/iced_graphics/latest/iced_graphics/font/struct.Source.html

The demos shipped with iced use that structure to modify the default font:

https://github.com/iced-rs/iced/blob/master/glow/src/text.rs#L29

but I have been unable to use it from outside iced.

What is the expected behavior?

It should be possible to select a font available on the OS without having to load your own .ttf.
