Could `position_dodge` have a `padding` argument?

Just as this is sometimes useful in position_dodge2, it could be useful at times in position_dodge

It would also be a way to have borders around dodged bars, and resolve issues with positioning noted in #5997

I think you can already specify padding using the width aesthetic and the position_dodge(width) parameter. Is there an example that is inconvenient where padding would alleviate some gnarlyness?

[davidhodge931]

Ah I see, I didn't think of this! No, I can't think of an example that could not be achieved by using that method.

Still though, conceptually, if position_dodge and position_dodge2 are intended to be the same other than the grouping variable thing, then they should have the same arguments? So, either add padding to position_dodge or deprecate it from position_dodge2 if not needed. Likewise for reverse.

So position_dodge2() needs a padding argument because it deals with variable-width data structures, whereas position_dodge() does not. For this reason, using width fixes the issue for position_dodge() but not position_dodge2().
The reverse argument has been added in #5932.
