set_node_filter

Sets the function to use as a node filter.

This is the most complex function to use for replaying nodes. It can either:

* keep the node and just return it unchanged

* create a replacement node and return that

* discard the node by returning `NULL`

* call [method@Gsk.RenderReplay.default] to have the default handler run for this node, which calls your function on its children

Parameters:

filter	the function to call to replay nodes
user_data	user data to pass to func
user_destroy	destroy notify that will be called to release the user data parameter
