gtk: Add gtk_widget_snapshot() It's functionally equivalent to gtk_widget_get_render_node() but uses a GtkSnapshot argument to carry the state.

snapshot: Change how gtk_snapshot_push/pop works Instead of appending a container node and adding the nodes to it as they come in, we now collect the nodes until gtk_snapshot_pop() is called and then hand them out in a container node. The caller of gtk_snapshot_push() is then responsible for doing whatever he wants with the created node. Another addigion is the keep_coordinates flag to gtk_snapshot_push() which allows callers to keep the current offset and clip region or discard it. Discarding is useful when doing transforms, keeping it is useful when inserting effect nodes (like the ones I'm about to add).

gsk: gsk_render_node_set_transform() => GskTransformNode Instead of having a setter for the transform, have a GskTransformNode. Most of the oprations that GTK does do not require a transform, so it doesn't make sense to have it as a primary attribute. Also, changing the transform requires updating the uniforms of the GL renderer, so we're happy if we can avoid that.
