Seifeddine Dridi updated FOP-2293:

    Attachment: FO_multi-switch_with_best-fit_extension.patch


* Added a basic implementation of FO multi-switch.
* Added new extension properties (fox:auto-toggle and fox:fitting-strategy) to 
FO multi-switch, which enable different handling of the set of mutli-case(s).
* New fitting strategy (any) added to best-fit; it loops over the mutli-case(s) 
and inserts any alternative that can be fitted inside the current page.
* Moved the core logic of the best-fit extension to PageBreakingAlgorithm, as 
suggested by Vincent.

_Current issues_
* Inserting inline content inside an FO multi-case makes FOP crash. This is 
because any inline tag should be wrapped inside a block-level container. The 
solution that I found so far, is that once the currently visible multi-case is 
known, we can insert it as a child of the parent of the FO multi-switch and 
remove the multi-switch altogether. But this doesn't work in case the best-fit 
extension is enabled.
* The extension does not yet support changing page IPD.

> I have been working on an extension for whitespace management, similar to 
> what's described here: 
> http://wiki.apache.org/xmlgraphics-fop/WhitespaceManagement
> The logic of the extension is very simple: the user defines a set of 
> alternatives that he wishes to insert at the end of a page, then if there is 
> enough space left, FOP will pick the alternative that best matches the user's 
> selection criteria (first fit, smallest fit, biggest fit).
> This is my first work on FOP and it took me almost 2 months to reach this 
> stage in development. But it's not the end of course, so I'm relying on your 
> feedback to improve it.
> Thank you
