                 Key: PIVOT-753
                 URL: https://issues.apache.org/jira/browse/PIVOT-753
             Project: Pivot
          Issue Type: Improvement
          Components: wtk
    Affects Versions: 2.0
         Environment: Windows XP SP3, OSX 10.6.7, RHEL 5.6
            Reporter: Roger Whitcomb
            Priority: Minor
             Fix For: 2.1


For long Label text that doesn't contain whitespace but with "wrapText:true" it 
would be nice to have an alternative place to wrap the text.

Possible Solutions:
- Provide a user-supplied "wrapChars" string containing suggested break 
characters
- Break on either whitespace or some combination of Character attributes (for 
instance: DASH_PUNCTUATION or CONNECTOR_PUNCTUATION)
- If there is no whitespace, then break at the exact boundary on whatever 
character is there (could be conditional on another "wrapAnywhere:true" style)
- Some combination of the above
- Use ellipsis as in PIVOT-623 without "wrapText" set.

Note: there was preliminary discussion of this issue as part of the comments in 
PIVOT-623.  Moved to a new issue to avoid further confusion of the original 
ellipsis issue there.
