Currently, the Button component supports appearance options such as size, fillMode, and rounded.

This request is about a way to set those appearance options globally for the entire app, in a single location, so that the user does not have to pass all of these settings every time they use a button.

I know this could be achieved by wrapping the Button component in another component, but that may lead to an unnecessary performance hit.

Another option would be to use the ThemeBuilder and set some variables, but that would not behave in the exact same way as the appearance options - for example, it is not so dynamic.
