[cairo] API proposal: cairo_copy_clip() and cairo_copy_clip_flat()

[Behdad Esfahbod]

As was raised in recent discussion on list, there is no
cairo_copy_clip() currently.  Since we added
cairo_copy_clip_rectangle_list() in 1.4 that may return
CAIRO_STATUS_CLIP_NOT_REPRESENTABLE, it's reasonable to add
cairo_copy_clip() to compliment that and give user full access to set
clip.

Also to follow cairo_copy_path() example, a cairo_copy_clip_flat() may
be added that flattens curves into line segments using current tolerance
setting (?).

Comments?  Patch?
