Browse source 
Features:
 * Define Minimap available modes (surface/radar, scale) from Lua, using player:set_minimap_modes()
 * New HUD elements for displaying minimap with custom size and placing
 * New minimap mode for displaying a texture instead of the map

If translation is chosen, texture is repeated horizontally to fill the whole element.
### `minimap`
Displays a minimap on the HUD.
* `size`: Size of the minimap to display. Minimap should be a square to avoid
distortion.
* `alignment`: The alignment of the minimap.
* `offset`: offset in pixels from position.

* `hud_set_hotbar_selected_image(texturename)`
* sets image for selected item of hotbar
* `hud_get_hotbar_selected_image`: returns texturename
* `set_minimap_modes({mode, mode, ...}, selected_mode)`
* Overrides the available minimap modes (and toggle order), and changes the
selected mode.
* `mode` is a table consisting of up to four fields:
* `type`: Available type:
* `off`: Minimap off
* `surface`: Minimap in surface mode
* `radar`: Minimap in radar mode
* `texture`: Texture to be displayed instead of terrain map
(texture is centered around 0,0 and can be scaled).
Texture size is limited to 512 x 512 pixel.
* `label`: Optional label to display on minimap mode toggle
The translation must be handled within the mod.
* `size`: Sidelength or diameter, in number of nodes, of the terrain
displayed in minimap
* `texture`: Only for texture type, name of the texture to display
* `scale`: Only for texture type, scale of the texture map in nodes per
pixel (for example a `scale` of 2 means each pixel represents a 2x2
nodes square)
* `selected_mode` is the mode index to be selected after modes have been changed
(0 is the first mode).
* `set_sky(parameters)`
* `parameters` is a table with the following optional fields:
* `base_color`: ColorSpec, changes fog in "skybox" and "plain".
