Rounded corner's side shadow issues
-----------------------------------

                 Key: TAPESTRY-1784
                 URL: https://issues.apache.org/jira/browse/TAPESTRY-1784
             Project: Tapestry
          Issue Type: Bug
          Components: Framework
    Affects Versions: 4.1.3
            Reporter: Christian Dutaret


I'm having trouble with side shadow generation:

1) Side shadows are always generated as PNG images.
2) Side shadows generate a white pixel border, which is fine if your background is white, but mine isn't...

For instance, consider a top left corner with a grey background and a lighter grey foreground:
/rounded?c=F8F8F8&bc=F2F2F2&w=17&h=17&a=tl&sw=2&o=.2

And the top side shadow:
/rounded?s=top&sw=2&o=.2

They don't fit side by side because of that white pixel border on the top side shadow.

So, if I may suggest a fix, could it be possible to add a background color parameter to the side shadow generation, which would:
- force generation as GIF
- generate the border pixel in the apropriate background color.
