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
Fixes some other third person camera specific attachments.
Implements a single new flag for entities to be forced visible in first person mode.
Old mods do not need to be updated to use the new flag and are fully backwards compatible.
This commit clarifies the maximal length of the serialized strings.
It will avoid accidental use of serializeString() when a larger string can be expected.
Removes unused Wide String serialization functions
Previously, the param2-controlled horizontal/vertical merge feature
(which was undocumented and forgotten) was always active, causing
uses of param2 other than "glasslikeliquidlevel" to affect H/V
merging.
Only respect H/V merge bits when paramtype2 = "glasslikeliquidlevel".
H/V merge bits and liquid level bits are designed to be used
simultaneously.
Moves the infotext depending on the value of the recent_chat_messages value + 2 additional lines to account for the 2 debug mode lines + 1 additional line as "buffer" for better readability if chat is full.
Erase all traces of normal "generation" from fragment shaders
Remove the "feature" from the engine and default config
Remove any leftover documentation of it
the event header seemingly being generic with libevent thus renaming it.
openal and opengl are deprecated on newer mac os releases thus suppressing the build warnings.
The inventory image size of the inventory image of nodes with drawtype allfaces (and related) is scaled as well if visual_scale is set (previously, the inventory image size was always the same)
Recent changes to collision code have changed the behaviour of the 'touching_ground'
bool in movement code. This had the effect of disabling camera smoothing when
'air stepheight' occurred when jumping onto a node while pressing forwards against
the node, causing an unpleasant sharp camera movement.
Rewrite the conditions for camera smoothing such that it is applied when jumping.
Fixes two bugs:
* The camera offset was not applied to an object while detaching, briefly placing the irrlicht matrixnode in world space.
* When attaching, the matrixnode's absolute position was evaluated without evaluating the parent first, resulting in zeroed positions.
