[Gnash-dev] invalidated bounds debugging

[strk]

I'm ready to add invalidated bounds testing to our
testsuite, but it seems I can't handle to understand the
mechanism of it.

What I would expect is that:

        0) get_invalidated_bounds is misnamed, should be
           expand_to_invalidated_bounds() as it actually
           expands the given rect to enclose the invalidated bounds.

        1) Before *any* ::advance() is called, the
           get_invalidated_bounds() should add NOTHING
           to the provided bounds.

        2) After *first* call to advance(), the get_invalidated_bounds()
           should turn the bounds into the WORLD bounds (everything changed)

        3) From *second* call on, the get_invalidated_bounds() should
           only add the boundaries of things that actually changed
           since when ? Last call to ::display ? Last call to
           get_invalidated_bounds () ??
