Subject: clip: consider all_clipped in _cairo_clip_get_extents
|
||
|
|
|
||
|
|
If the gstate clip in _cairo_gstate_int_clip_extents() has all_clipped
|
||
|
|
set (and path NULL), then it returns the gstate target extents instead of
|
||
|
|
an empty rectangle. If the target is infinite, then it says the clip is
|
||
|
|
unbounded.
|
||
|
|
|
||
|
