Yes, the overdraw will be optional and it may be up to the platform layer=
=20
to enable it.

Perhaps overdraw is completely determined by the platform layer. Or there=
=20
could be an API.

The decision could be a combination of the platform layer and an API.

There are other APIs like `SCI_SETTECHNOLOGY` and `SCI_SETBIDIRECTIONAL`=20
where some platform layers intercept the call to restrict the possibilities=
=20
such as refusing bidirectional mode.

Sometimes scaling information is available at an application level but is=
=20
not easily available from a widget. On Win32, for example, some messages=20
only go to topmost windows.

In the opposite direction, requiring applications to use an API means this=
=20
will be less automatic which will lead to a poorer default experience.

The patch does not include an API or any platform enabling since its just=
=20
trying to see if the idea is workable.
