[bug #19352] Cairo: bad EPS from NSView_dataWithEPSInsideRect:

[Mark Tracy]

Follow-up Comment #16, bug #19352 (project gnustep):

Not waiting for cairo, I hacked my own cairo_clone() function that faithfully
copies the clip, and used it in [CairoGState -copyWithZone:]. While it
continued to display to the screen OK, the printing got worse, not better. It
appears that the bounding box is not correctly computed from the paper size
and margins. Furthermore, one of the clipping rectangles is misplaced
vertically. The problem is especially severe when trying to print a small view
on a larger piece of paper; the clipping rectangles do not intersect, so
nothing prints at all. You can demonstrate this with TestApp by playing with
the window size and paper size.

When I use cairo_reset_clip() after cairo_clone(), the printing behavior is
the same as the original. There are still some errors in clipping and
placement, but not so severe. For most cases, the worst problem is wrong
margins.

My cairo hack is probably not suitable for general use. It may be handy to
see what is wrong while waiting for the official cairo_copy_clip() to appear.
