### Timing
* `minetest.after(time, func, ...)`
* `nodenames`: e.g. `{"ignore", "group:tree"}` or `"default:dirt"`

- * First return value: Table with all node positions
- * Second return value: Table with the count of each node with the node name
- as index.
+ * If `grouped` is true the return value is a table indexed by node name
+ which contains lists of positions.
+ * If `grouped` is false or absent the return values are as follows:
+ first value: Table with all node positions
+ second value: Table with the count of each node with the node name
+ as index

### Player
-* `minetest.get_wielded_item()`
- * Returns the itemstack the local player is holding
* `minetest.send_chat_message(message)`
* Act as if `message` was typed by the player into the terminal.
* `minetest.run_server_chatcommand(cmd, param)`
* Unserializable things like functions and userdata are saved as null.
* **Warning**: JSON is more strict than the Lua table format.
1. You can only use strings and positive integers of at least one as keys.
- 2. You can not mix string and integer keys.
+ 2. You cannot mix string and integer keys.
This is due to the fact that JSON has two distinct array and object values.
* Example: `write_json({10, {a = false}})`, returns `"[10, {\"a\": false}]"`
* `minetest.serialize(table)`: returns a string
* Compress a string of data.
* `method` is a string identifying the compression method to be used.
* Supported compression methods:
- * Deflate (zlib): `"deflate"`

- * Deflate: `level` - Compression level, `0`-`9` or `nil`.
+ * Deflate (zlib): `"deflate"`
+ * Zstandard: `"zstd"`
+ * `...` indicates method-specific arguments. Currently defined arguments
+ are:
+ * Deflate: `level` - Compression level, `0`-`9` or `nil`.
+ * Zstandard: `level` - Compression level. Integer or `nil`. Default `3`.
+ Note any supported Zstandard compression level could be used here,
+ but these are subject to change between Zstandard versions.

Escape sequences
----------------
-Most text can contain escape sequences, that can for example color the text.
+Most text can contain escape sequences that can for example color the text.
There are a few exceptions: tab headers, dropdowns and vertical labels can't.
The following functions provide escape sequences:
* `minetest.get_color_escape_sequence(color)`:
Named colors are also supported and are equivalent to
[CSS Color Module Level 4](http://dev.w3.org/csswg/css-color/#named-colors).
-To specify the value of the alpha channel, append `#AA` to the end of the color name
-(e.g. `colorname#08`). For named colors the hexadecimal string representing the alpha
-value must (always) be two hexadecimal digits.
+To specify the value of the alpha channel, append `#A` or `#AA` to the end of
+the color name (e.g. `colorname#08`).
`Color`
-------------
* `offset`: offset in pixels from position.
### `waypoint`
+
Displays distance to selected world position.
* `name`: The name of the waypoint.
* `text`: Distance suffix. Can be blank.
-* `number:` An integer containing the RGB value of the color used to draw the text.
+* `precision`: Waypoint precision, integer >= 0. Defaults to 10.
+ If set to 0, distance is not shown. Shown value is `floor(distance*precision)/precision`.
+ When the precision is an integer multiple of 10, there will be `log_10(precision)` digits after the decimal point.
+ `precision = 1000`, for example, will show 3 decimal places (eg: `0.999`).
+ `precision = 2` will show multiples of `0.5`; precision = 5 will show multiples of `0.2` and so on:
+ `precision = n` will show multiples of `1/n`
+* `number:` An integer containing the RGB value of the color used to draw the
+ text.
+* `world_pos`: World position of the waypoint.
+* `offset`: offset in pixels from position.
+* `alignment`: The alignment of the waypoint.
+
+### `image_waypoint`
+
+Same as `image`, but does not accept a `position`; the position is instead determined by `world_pos`, the world position of the waypoint.
+
+* `scale`: The scale of the image, with 1 being the original texture size.
+ Only the X coordinate scale is used (positive values).
+ Negative values represent that percentage of the screen it
+ should take; e.g. `x=-100` means 100% (width).
+* `text`: The name of the texture that is displayed.
+* `alignment`: The alignment of the image.
* `world_pos`: World position of the waypoint.
+* `offset`: offset in pixels from position.
