-API documentation for the HUD bars mod 1.2.1
-============================================
-
-## Introduction
-This API allows you to add, change, hide and unhide custom HUD bars for this mod.
-
-## Overview
-To give you a *very* brief overview over this API, here is the basic workflow on how to add your own custom HUD bar:
-
-* Create images for your HUD bar
-* Call `hb.register_hudbar` to make the definition of the HUD bar known to this mod
-* Call `hb.init_hudbar` for each player for which you want to use previously defined HUD bar
-* Use `hb.change_hudbar` whenever you need to change the values of a HUD bar of a certain player
-* If you need it: Use `hb.hide_hudbar` and `hb.unhide_hudbar` to hide or unhide HUD bars of a certain player
-
-## The basic rules
-In order to use this API, you should be aware of a few basic rules in order to understand it:
-
-* A HUD bar is an approximate graphical representation of the ratio of a current value and a maximum value, i.e. current health of 15 and maximum health of 20. A full HUD bar represents 100%, an empty HUD bar represents 0%.
-* The current value must always be equal to or smaller then the maximum 
-* Both current value and maximum must not be smaller than 0
-* Both current value and maximum must be real numbers. So no NaN, infinity, etc.
-* The HUD bar will be hidden if the maximum equals 0. This is intentional.
-* The health and breath HUD bars are hardcoded.
-
-These are soft rules, the HUD bars mod will not enforce all of these.
-But this mod has been programmed under the assumption that these rules are followed, for integrity.
-
-## Adding a HUD bar
-To make a new HUD bar known to this mod, you need …
-
-* … an image of size 2×16 for the bar
-* … an icon of size 16×16 (optional)
-* … to register it with `hb.register_hudbar`
-
-### Bar image
-The image for the bar will be repeated horizontally to denote the “value” of the HUD bar.
-It **must** be of size 2×16.
-If neccessary, the image will be split vertically in half, and only the left half of the image
-is displayed. So the final HUD bar will always be displayed on a per-pixel basis.
-
-The default bar images are single-colored, but you can use other styles as well, for instance,
-a vertical gradient.
-
-### Icon
-A 16×16 image shown left of the HUD bar. This is optional.
-
-### `hb.register_hudbar(identifier, text_color, label, textures, default_start_value, default_start_max, default_start_hidden, format_string)`
-This function registers a new custom HUD bar definition to the HUD bars mod, so it can be later used to be displayed, changed, hidden
-and unhidden on a per-player basis.
-Note this does not yet display the HUD bar.
-
-The HUD bars will be displayed in a “first come, first serve” order. This mod does not allow fow a custom order or a way to set it
-manually in a reliable way.
-
-
-#### Parameters
-* `identifier`: A globally unique internal name for the HUD bar, will be used later to refer to it. Please only rely on alphanumeric characters for now. The identifiers “`health`” and “`breath`” are used internally for the built-in health and breath bar, respectively. Please do not use these names.
-* `text_color`: A 3-octet number defining the color of the text. The octets denote, in this order red, green and blue and range from `0x00` (complete lack of this component) to `0xFF` (full intensity of this component). Example: `0xFFFFFF` for white.
-* `label`: A string which is displayed on the HUD bar itself to describe the HUD bar. Try to keep this string short.
-* `textures`: A table with the following fields:
- * `bar`: The file name of the bar image (as string). This is only used for the `progress_bar` bar type (see `README.txt`, settings section).
- * `icon`: The file name of the icon, as string. For the `progress_bar` type, it is shown as single image left of the bar, for the two statbar bar types, it is used as the statbar icon and will be repeated. This field can be `nil`, in which case no icon will be used, but this is not recommended, because the HUD bar will be invisible if the one of the statbar bar types is used.
- * `bgicon`: The file name of the background icon, it is used as the background for the modern statbar mode only. This field can be `nil`, in which case no background icon will be displayed in this mode.
-* `default_start_value`: If this HUD bar is added to a player, and no initial value is specified, this value will be used as initial current value
-* `default_max_value`: If this HUD bar is added to a player, and no initial maximum value is specified, this value will be used as initial maximum value
-* `default_start_hidden`: The HUD bar will be initially start hidden by default when added to a player. Use `hb.unhide_hudbar` to unhide it.
-* `format_string`: This is optional; You can specify an alternative format string display the final text on the HUD bar. The default format string is “`%s: %d/%d`” (in this order: Label, current value, maximum value). See also the Lua documentation of `string.format`.
-
-#### Return value
-Always `nil`.
-
-
-## Displaying a HUD bar
-After a HUD bar has been registered, they are not yet displayed yet for any player. HUD bars must be
-explicitly initialized on a per-player basis.
-
-You probably want to do this in the `minetest.register_on_joinplayer`.
-
-### `hb.init_hudbar(player, identifier, start_value, start_max, start_hidden)`
-This function initialzes and activates a previously registered HUD bar and assigns it to a
-certain client/player. This has only to be done once per player and after that, you can change
-the values using `hb.change_hudbar`.
-
-However, if `start_hidden` was set to `true` for the HUD bar (in `hb.register_hudbar`), the HUD bar
-will initially be hidden, but the HUD elements are still sent to the client. Otherwise,
-the HUD bar will be initially be shown to the player.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the new HUD bar should be displayed to.
-* `identifier`: The identifier of the HUD bar type, as specified in `hb.register_hudbar`.
-* `start_value`: The initial current value of the HUD bar. This is optional, `default_start_value` of the registration function will be used, if this is `nil`.
-* `start_max`: The initial maximum value of the HUD bar. This is optional, `default_start_max` of the registration function will be used, if this is `nil`
-* `start_hidden`: Whether the HUD bar is initially hidden. This is optional, `default_start_hidden` of the registration function will be used as default
-
-#### Return value
-Always `nil`.
-
-
-
-## Modifying a HUD bar
-After a HUD bar has been added, you can change the current and maximum value on a per-player basis.
-You use the function `hb.change_hudbar` for this.
-
-### `hb.change_hudbar(player, identifier, new_value, new_max_value)`
-Changes the values of an initialized HUD bar for a certain player. `new_value` and `new_max_value`
-can be `nil`; if one of them is `nil`, that means the value is unchanged. If both values
-are `nil`, this function is a no-op.
-This function also tries minimize the amount of calls to `hud_change` of the Minetest Lua API, and
-therefore, network traffic. `hud_change` is only called if it is actually needed, i.e. when the
-actual length of the bar or the displayed string changed, so you do not have to worry about it.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to change, as specified in `hb.register_hudbar`.
-* `new_value`: The new current value of the HUD bar
-* `new_max_value`: The new maximum value of the HUD bar
-
-#### Return value
-Always `nil`.
-
-
-## Hiding and unhiding a HUD bar
-You can also hide custom HUD bars, meaning they will not be displayed for a certain player. You can still
-use `hb.change_hudbar` on a hidden HUD bar, the new values will be correctly displayed after the HUD bar
-has been unhidden. Both functions will only call `hud_change` if there has been an actual change to avoid
-unneccessary traffic.
-
-Note that the hidden state of a HUD bar will *not* be saved by this mod on server shutdown, so you may need
-to write your own routines for this or by setting the correct value for `start_hidden` when calling
-`hb.init_hudbar`.
-
-### `hb.hide_hudbar(player, identifier)`
-Hides the specified HUD bar from the screen of the specified player.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`.
-
-#### Return value
-Always `nil`.
-
-
-### `hb.unhide_hudbar(player, identifier)`
-Makes a previously hidden HUD bar visible again to a player.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to unhide, as specified in `hb.register_hudbar`.
-
-#### Return value
-Always `nil`.
-
-
-## Reading HUD bar information
-It is also possible to read information about an active HUD bar.
-
-### `hb.get_hudbar_state(player, identifier)`
-Returns the current state of the active player's HUD bar.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`.
-
-#### Return value
-A table which holds information on the current state of the HUD bar. Note the table is a deep
-copy of the internal HUD bar state, it is *not* a reference; the information hold by the table is
-only true for the moment you called this function. The fields of this table are:
-
-* `value`: Current value of HUD bar.
-* `max`: Current maximum value of HUD bar.
-* `hidden`: Boolean denoting whether the HUD bar is hidden.
-* `barlength`: The length of the HUD bar in pixels. This field is meaningless if the HUD bar is currently hidden.
-* `text`: The text shown on the HUD bar. This fiels is meaningless if the HUD bar is currently hidden.

-Minetest mod: HUD bars
-======================
-Version: 1.2.1
-
-This software uses semantic versioning, as defined by version 2.0.0 of the SemVer
-standard. <http://semver.org/>
-
-
-License of source code: WTFPL
------------------------------
-Author: Wuzzy (2015)
-Forked from the “Better HUD” [hud] mod by BlockMen.
-
-
-Using the mod:
---------------
-This mod changes the HUD of Minetest. It replaces the default health and breath symbols by horizontal colored bars with text showing
-the number.
-
-Furthermore, it enables other mods to add their own custom bars to the HUD, this mod will place them accordingly.
-
-You can create a “hudbars.conf” file to customize the positions of the health and breath bars. Take a look at “hudbars.conf.example”
-to get more infos. The lines starting with “--” are comments, remove the two dashes to activate a setting. Settings which are not
-set will use a default value instead.
-
-
-IMPORTANT:
-Keep in mind if running a server with this mod, that the custom position should be displayed correctly on every screen size!
-
-Settings:
----------
-This mod can be configured by editing minetest.conf. Currently, the following setting is recognized:
-
-- hudbars_autohide_breath: A boolean setting, it can be either “true” or “false”. If set to “true”,
-  the breath bar will be automatically hidden shortly after the breathbar has been filled up. If set
-  to “false”, the breath bar will always be displayed. The default value is “true”.
-
-- hudbars_sorting: This setting allows you to specify the “slot” positions of the HUD bars manually.
-
-  The setting has to be specified as a comma-seperated list of key=value pairs, where a key refers to the
-  identifier of a HUD bar and the value refers to the slot number of where the HUD bar should be placed.
-  The slot number must be an integer greater of equal to 0. The slot positions start (slot 0) at the
-  bottom (nearest to hotbar in default configuration) left side, the following slot 1 is at the right
-  side, slot `2` is on the right side again, but placed over the first HUD bar (slot 0), and it goes on,
-  in a zig-zag pattern.
-  All HUD bars to which no sorting rule has been applied will fill in all slots which have not been occupied
-  by the HUD bars specified in this setting, the slots will be filled in from the lowest slot number.
-  Note that the order of those remaining HUD bars is *not* fixed, it basically just boils down on which mod
-  “came” first. Don't worry, the mod will still work perfectly fine, this setting is entirely optional.
-
-  Be careful not to use slot indices twice, or else different HUD bars will be drawn over each other!
-
-  If this setting is not set, by default the health and breath bar are displayed at slot positions 0 and 1,
-  respectively (health bar at left bottom-most positoin, breath bar right from it). All other HUD bars are
-  placed automatically.
-
-  Example value:
-    breath=0, health=1
-  This places the breath bar at the left side, and the health bar to the right side.
-
-- hudbars_bar_type: Specifies the style of bars. You can select between the default progress-bar-like bars and the good old statbars
-  like you know from vanilla Minetest. Note that the classic and modern statbars are still a little bit experimental.
-  These values are possible:
-    - progress_bar:    A horizontal progress-bar-like bar with a label, showing numerical value (current, maximum), and an icon.
-                       These bars usually convey the most information. This is the default and recommended value..
-    - statbar_classic: Classic statbar, like in vanilla Minetest. Made out of up to 20 half-symbols. Those bars represent the vague ratio between
-                       the current value and the maximum value. 1 half-symbol stands for approximately 5% of the maximum value.
-    - statbar_modern:  Like the classic statbar, but also supports background images, this kind of statbar may be considered to be more user-friendly
-                       than the classic statbar. This bar type closely resembles the [hud] mod.
-
-- hudbars_vmargin: The vertical distance between two HUD bars in pixels (default: 24)
-- hudbars_tick: The number of seconds between two updates of the HUD bars. Increase this number if you have a slow server (default: 0.1)
-
-Position settings:
-With these settings you can configure the positions of the HUD bars. All settings must be specified as a number.
-The pos settings are specified as a floating-point number between 0 to 1 each, the start_offset settings are
-specified as whole numbers, they specify a number of pixels.
-The left and right variants are used for the zig-zag mode. In the stack_up and stack_down modes, only the left variant is used for
-the base position
-
-- hudbars_pos_left_x, hudbars_pos_left_y: Screen position (x and y) of the left HUD bar in zigzag mode. 0 is left-most/top, 1 is right-most/bottom.
-	Defaults: 0.5 (x) and 1 (y)
-- hudbars_pos_right_x, hudbars_pos_right_y: Same as above, but for the right one.
-	Defaults: 0.5 and 1.
-- hudbars_start_offset_left_x, hudbars_start_offset_left_y: Offset in pixels from the basic screen position specified in hudbars_pos_left_x/hudbars_pos_left_y.
-	Defaults: -175 and -86
-- hudbars_start_offset_right_x, hudbars_start_offset_right_y: Same as above, but for the right one.
-	Defaults: 15 and -86
