[Style][Salt] Allow full style on salt

Question

Hello PlantUML team,

• Could you allow style on salt Diagram?

Here is an example (from debug style skin) or a proposal for the keyword (change root to saltDiagram, ,...):

@startsalt
<style>
root {
  FontName SansSerif
  HyperLinkColor green
  FontColor red
  FontSize 19
  FontStyle plain
  HorizontalAlignment right
  RoundCorner 15
  DiagonalCorner 10
  LineColor #3600A8
  LineThickness 3.0
  BackGroundColor #pink
  Shadowing 1.0
  Margin 10
  Padding 20
}
</style>
{#
{* File | Edit | Source | Refactor
 Refactor | New | Open File | - | Close | Close All }
{/ General | Fullscreen | Behavior | Saving }
{
{ Open image in: | ^Smart Mode^ }
[X] Smooth images when zoomed
[X] Confirm image deletion
[ ] Show hidden images
}
[Close]
{#
. | Column 2 | Column 3
Row header 1 | value 1 | value 2
Row header 2 | A long cell | *
}
}
@endsalt

Thanks for your works,
Regards,
