 		Canvas items are drawn in tree order. By default, children are on top of their parents so a root [CanvasItem] will be drawn behind everything. This behavior can be changed on a per-item basis.
 		A [CanvasItem] can also be hidden, which will also hide its children. It provides many ways to change parameters such as modulation (for itself and its children) and self modulation (only for itself), as well as its blend mode.
 		Ultimately, a transform notification can be requested, which will notify the node that its global position changed in case the parent tree changed.

With the exception of [code]1[/code], only power-of-two values are valid ([code]2[/code], [code]4[/code], [code]8[/code], [code]16[/code]). A value of [code]1[/code] forcibly disables anisotropic filtering, even on textures where it is enabled.
+			[b]Note:[/b] For performance reasons, anisotropic filtering [i]is not enabled by default[/i] on textures. For this setting to have an effect, anisotropic texture filtering can be enabled by selecting a texture in the FileSystem dock, going to the Import dock, checking the [b]Anisotropic[/b] checkbox then clicking [b]Reimport[/b]. However, anisotropic filtering is rarely useful in 2D, so only enable it for textures in 2D if it makes a meaningful visual difference.

+		[b]Terminology:[/b] In the context of UPnP networking, "gateway" (or "internet gateway device", short IGD) refers to network devices that allow computers in the local network to access the internet ("wide area network", WAN). These gateways are often also called "routers".
+		[b]Pitfalls:[/b]
+		- As explained above, these calls are blocking and shouldn't be run on the main thread, especially as they can block for multiple seconds at a time. Use threading!
+		- Networking is physical and messy. Packets get lost in transit or get filtered, addresses, free ports and assigned mappings change, and devices may leave or join the network at any time. Be mindful of this, be diligent when checking and handling errors, and handle these gracefully if you can: add clear error UI, timeouts and re-try handling.
+		- Port mappings may change (and be removed) at any time, and the remote/external IP address of the gateway can change likewise. You should consider re-querying the external IP and try to update/refresh the port mapping periodically (for example, every 5 minutes and on networking failures).
+		- Not all devices support UPnP, and some users disable UPnP support. You need to handle this (e.g. documenting and requiring the user to manually forward ports, or adding alternative methods of NAT traversal, like a relay/mirror server, or NAT hole punching, STUN/TURN, etc.).
+		- Consider what happens on mapping conflicts. Maybe multiple users on the same network would like to play your game at the same time, or maybe another application uses the same port. Make the port configurable, and optimally choose a port automatically (re-trying with a different port on failure).
+		[b]Further reading:[/b] If you want to know more about UPnP (and the Internet Gateway Device (IGD) and Port Control Protocol (PCP) specifically), [url=https://en.wikipedia.org/wiki/Universal_Plug_and_Play]Wikipedia[/url] is a good first stop, the specification can be found at the [url=https://openconnectivity.org/developer/specifications/upnp-resources/upnp/]Open Connectivity Foundation[/url] and Godot's implementation is based on the [url=https://github.com/miniupnp/miniupnp]MiniUPnP client[/url].

-				Adds a mapping to forward the external [code]port[/code] (between 1 and 65535) on the default gateway (see [method get_gateway]) to the [code]internal_port[/code] on the local machine for the given protocol [code]proto[/code] (either [code]TCP[/code] or [code]UDP[/code], with UDP being the default). If a port mapping for the given port and protocol combination already exists on that gateway device, this method tries to overwrite it. If that is not desired, you can retrieve the gateway manually with [method get_gateway] and call [method add_port_mapping] on it, if any.
+				Adds a mapping to forward the external [code]port[/code] (between 1 and 65535, although recommended to use port 1024 or above) on the default gateway (see [method get_gateway]) to the [code]internal_port[/code] on the local machine for the given protocol [code]proto[/code] (either [code]TCP[/code] or [code]UDP[/code], with UDP being the default). If a port mapping for the given port and protocol combination already exists on that gateway device, this method tries to overwrite it. If that is not desired, you can retrieve the gateway manually with [method get_gateway] and call [method add_port_mapping] on it, if any. Note that forwarding a well-known port (below 1024) with UPnP may fail depending on the device.
+				Depending on the gateway device, if a mapping for that port already exists, it will either be updated or it will refuse this command due to that conflict, especially if the existing mapping for that port wasn't created via UPnP or points to a different network address (or device) than this one.
 				If [code]internal_port[/code] is [code]0[/code] (the default), the same port number is used for both the external and the internal port (the [code]port[/code] value).
-				The description ([code]desc[/code]) is shown in some router UIs and can be used to point out which application added the mapping. The mapping's lease duration can be limited by specifying a [code]duration[/code] (in seconds). However, some routers are incompatible with one or both of these, so use with caution and add fallback logic in case of errors to retry without them if in doubt.
+				The description ([code]desc[/code]) is shown in some routers management UIs and can be used to point out which application added the mapping.
+				The mapping's lease [code]duration[/code] can be limited by specifying a duration in seconds. The default of [code]0[/code] means no duration, i.e. a permanent lease and notably some devices only support these permanent leases. Note that whether permanent or not, this is only a request and the gateway may still decide at any point to remove the mapping (which usually happens on a reboot of the gateway, when its external IP address changes, or on some models when it detects a port mapping has become inactive, i.e. had no traffic for multiple minutes). If not [code]0[/code] (permanent), the allowed range according to spec is between [code]120[/code] (2 minutes) and [code]86400[/code] seconds (24 hours).
