Note that calling cairo_reset_clip() on the resulting #cairo_t will
produce undefined results, so avoid it at all costs.
Typically, this function is used to draw on a #GdkWindow out of the paint
cycle of the toolkit; this should be avoided, as it breaks various assumptions
and optimizations.
If you are drawing on a native #GdkWindow in response to a %GDK_EXPOSE event
you should use gdk_window_begin_draw_frame() and gdk_drawing_context_get_cairo_context()
instead. GTK will automatically do this for you when drawing a widget.
