Please provide a skinparam to set a padding in pixels between participants and boxes on sequence diagrams

I'd like to specify a "padding" in pixels between participants and boxes, e.g.

@startuml
skinparam ParticipantPadding 10
skinparam BoxPadding 20

box "B"
participant Alice
end box

Alice -> Bob : hello
@enduml

Thanks for the suggestion.

We like the idea of adding padding option, so here is a new beta:
https://dl.dropboxusercontent.com/u/13064071/plantuml.jar

This beta works with the following diagram:

@startuml
skinparam ParticipantPadding 10
skinparam BoxPadding 20

box "B"
participant Alice
end box

Alice -> Bob : hello
@enduml

This kind of modification is quite easy to do (when you are used to PlantUML code...), so we did it directly.
The setting can be set in pixel only (which is consistent other values).

Other padding settings may be implemented on demand, so please ask!

Regards

Was this rolled out? In 1.2018.10 I don't see these parameters, but I would like to use them!

```
$> plantuml -language | grep -i pad
Padding
```

```

It is.
We just have to update the -language output.
BTW graphviz 2.40.1 has issues with PlantUML. You may consider downgrade to 2.38

Would it be possible to implement padding for packages in component diagrams? It doesn't seem to be settable on packages in general or on individual packages - only globally on all elements through "skinparam Padding".

Also, when I set padding globally through "skinparam Padding" - it gets applied to packages, but there seems to be a bug where only top and bottom padding gets applied, but not on the sides of the package.

And there's another bug where packages aren't properly padded to accommodate interface text label, e.g. with this example:

@startuml

package "Application process" {

  component [Application] as Application

  interface "Some API" as API1
  [Some provider] as Provider

  API1 - Provider
  Application --> API1

} 

@enduml

The result looks like this:
