Description thb 2009-10-15 23:52:57 UTC 
Generic polygon clipping is hard (cf. floating point accuracy). Clipping
axis-aligned boxes is much easier, and a quite common task e.g. for wmf/emf
import. This patch adds functionality for that to basegfx.
Comment 1 thb 2009-10-16 00:10:35 UTC 
Split up into several commits:

commit 76e16f751771 adds the specialized box clipper class & tests
commit 940ec0795198 adds special clip-state class for general output device clip
state handling, and makes use of that from inside slideshow.

commit e2573ed7c7ae is slightly unrelated, but greatly speeds up the basegfx svg
polygon export (quite useful for the unit tests)

Comment 3 thb 2010-02-19 21:54:18 UTC 
@aw: please have a look at that feature, too. extensive unit testing is in
place, but well... ;)
