<div>
<pre>In Cairo release 1.10.0, cairo_region_t data type was added.
However pixman was removed.
Now there is no way to use cairo_region_t in cairo_context. So cairo_region is
just a reflection of rectangles.
Setting the CLIP region to the cairo_region is not possible. So if we have a
cairo_region_t created after union, subtract, we cannot use it for clipping
purposes.
Currently cairo_clip(_preserve) can use ONLY path, but cannot make use all
rectangles (obtained from cairo_region_t).
By some or other way, we need to create/expose a function
cairo_clip_intersect_to_region (cairo_region_t *region), which would clip
according to PATH and INTERSECT with region</pre>
