[Libreoffice] [REVIEW] 4 minutes 27 seconds -> 11 seconds

[Caolán McNamara]

cmc->thb: I had some .doc documents which were awesomely slow to load
up, apparently because some polygons had to be split up into large
polypolygons due to a custom dashed line in use to draw them or
something of that nature.

Could you double check my change to basegfx2

I'm *sure* its good, but the scale of speed-up from 4 minutes 27 seconds
to 11 seconds is massively more than I expected. Especially as the
insert point is at the end, rather than at the beginning or middle which
would have required a lot of memmove type operations.
