public void push_isolation (Isolation features)
Isolates the following drawing operations from previous ones.
You can express "everything but these flags" in a forward compatible way by using bit math: `GSK_ISOLATION_ALL & ~( GSK_ISOLATION_BACKGROUND | GSK_ISOLATION_COPY_PASTE)` will isolate everything but background and copy/paste.
For what isolation features exist, see [flags@Gsk.Isolation].
Content is isolated until the next call to [method@Gtk.Snapshot.pop].
