For solid nodes, the lighting at a corner becomes face-dependent, which
means that only the four nodes in face-direction contribute to the
lighting (getSmoothLightSolid).
For special nodes, which use the lighting values at the eight corners of
a node, the lighting is not face-dependent, but certain nodes of the
eight surrounding nodes of a corner (here indices 4, 5, 6 and 7) can be
obstructed.
Ambient occlusion now also occurs for solid nodes, if two, three or four
of the four nodes in face-direction are solid.
Useful for underwater plants.
Node consists of a base cube plus a plantlike extension that can pass through
liquid nodes above without creating air bubbles or interfering with liquid flow.
Uses paramtype2 'leveled', param2 defines height of plantlike extension.

More singleton work
RenderingEngine owns draw_load_screen
move draw functions to RenderingEngine
Reduce IrrlichtDevice exposure and guienvironment
RenderingEngine: Expose get_timer_time() to remove device from guiEngine
Make irrlichtdevice & scene manager less exposed

* Optimize updateFastFaceRow processing by removing some TileSpec copy
It permit to decrease this function from 54% runtime to 45% and reduce copy from 14% runtime to 12.5%
getTileInfo also reduced from 27% to 23%
* makeFastFace should use a const ref too
this trigger a const pointer need in the underlying function
Also fix some code style and prevent calculating 4 times the same position at a point
* Reduce a comparison cost for lights in updateFastFaceRow
Add the missing paramtype2 for param2 controlling the liquid level
inside the glasslike_framed drawtype.
Add missing documentation of the feature to lua_api.txt.
Update and improve comments for drawtype enumerations in nodedef.h.
This re-applies 2 commits that were reverted.
Visual_scale was applied twice to plantlike by accident sometime between
2011 and 2013, squaring the requested scale value. Visual_scale is
correctly applied once in it's other uses in signlike and torchlike.
Two lines of code are removed, they also had no effect for the vast
majority of nodes with the default visual_scale of 1.0.
The texture continues to have it's base at ground level.
Send sqrt(visual_scale) to old clients.
Keep compatibility with protocol < 30 clients now that visual_scale
is no longer applied twice to plantlike drawtype and mods are being
updated to a new value.

- Increase ContentFeatures serialization version
- Color property and palettes for nodes
- paramtype2 = "color", "colored facedir" or "colored wallmounted"
* Environment code refactoring
* Cleanup includes & class declarations in client & server environment to improve build speed
* ServerEnvironment::m_gamedef is now a pointer to Server instead of IGameDef, permitting to cleanup many casts.
* Cleanup IGameDef
* Move ITextureSource* IGameDef::getTextureSource() to Client only.
* Also move ITextureSource *IGameDef::tsrc() helper
* drop getShaderSource, getSceneManager, getSoundManager & getCamera abstract call
* drop unused emerge() call
* cleanup server unused functions (mentionned before)
* Drop one unused parameter from ContentFeatures::updateTextures
* move checkLocalPrivilege to Client
* Remove some unnecessary casts
* create_formspec_menu: remove IWritableTextureSource pointer, as client already knows it
* Fix some comments
* Change required IGameDef to Server/Client pointers
* Previous change that game.cpp sometimes calls functions with Client + InventoryManager + IGameDef in same functions but it's the same objects
* Remove duplicate Client pointer in GUIFormSpecMenu::GUIFormSpecMenu
* drop ClientMap::sectorWasDrawn which is unused
Adds several new ways that the plantlike drawtype mesh can be changed.
This requires paramtype2 = "meshoptions" to be set in the node
definition. The drawtype for these nodes should be "plantlike".
These modifications are all done using param2. This field is now
a complex bitfield that allows some or more of the combinations to
be chosen, and the mesh draw code will choose the options based as
neeeded for each plantlike node.
bit layout:
bits 0, 1 and 2 (values 0x1 through 0x7) are for choosing the plant
mesh shape:
0 - ordinary plantlike plant ("x" shaped)
1 - ordinary plant, but rotated 45 degrees ("+" shaped)
2 - a plant with 3 faces ("*" shaped)
3 - a plant with 4 faces ("#" shaped)
4 - a plant with 4 faces ("#" shaped, leaning outwards)
5 through 7 are unused and reserved for future mesh shapes.
bit 3 (0x8) causes the plant to be randomly offset in the x,z
plane. The plant should fall within the 1x1x1 nodebox if regularly
sized.
bit 4 (0x10) causes the plant mesh to grow by sqrt(2), and will cause
the plant mesh to fill out 1x1x1, and appear slightly larger. Texture
makers will want to make their plant texture 23x16 pixels to have the
best visual fit in 1x1x1 size.
bit 5 (0x20) causes each face of the plant to have a slight negative
Y offset in position, descending up to 0.125 downwards into the node
below. Because this is per face, this causes the plant model to be
less symmetric.
bit 6 (0x40) through bit 7 (0x80) are unused and reserved for
future use.

NDT_CONNECTED attempts to connect to any side of nodes that it can
connect to, which is troublesome for FACEDIR type nodes that generally
may only have one usable face, and can be rotated.
We introduce a node parameter `connect_sides` that is valid for
any node type. If specified, it lists faces of the node (in "top",
"bottom", "front", "left", "back", "right", form, as array) that
connecting nodeboxes can connect to. "front" corresponds to the south
facing side of a node with facedir = 0.
If the node is rotatable using *simple* FACEDIR, then the attached
face is properly rotated before checking. This allows e.g. a chest
to be attached to only from the rear side.
We introduce a new nodebox type "connected", and allow these nodes to
have optional nodeboxes that connect it to other connecting nodeboxes.
This is all done at scenedraw time in the client. The client will
inspect the surrounding nodes and if they are to be connected to,
it will draw the appropriate connecting nodeboxes to make those
connections.
In the node_box definition, we have to specify separate nodeboxes for
each valid connection. This allows us to make nodes that connect only
horizontally (the common case) by providing optional nodeboxes for +x,
-x, +z, -z directions. Or this allows us to make wires that can connect
up and down, by providing nodeboxes that connect it up and down (+y,
-y) as well.
The optional nodeboxes can be arrays. They are named "connect_top,
"connect_bottom", "connect_front", "connect_left", "connect_back" and
"connect_right". Here, "front" means the south facing side of the node
that has facedir = 0.
Additionally, a "fixed" nodebox list present will always be drawn,
so one can make a central post, for instance. This "fixed" nodebox
can be omitted, or it can be an array of nodeboxes.
Collision boxes are also updated in exactly the same fashion, which
allows you to walk over the upper extremities of the individual
node boxes, or stand really close to them. You can also walk up
node noxes that are small in height, all as expected, and unlike the
NDT_FENCELIKE nodes.
I've posted a screenshot demonstrating the flexibility at
http://i.imgur.com/zaJq8jo.png
In the screenshot, all connecting nodes are of this new subtype.
Transparent textures render incorrectly, Which I don't think is
related to this text, as other nodeboxes also have issues with this.
A protocol bump is performed in order to be able to send older clients
a nodeblock that is usable for them. In order to avoid abuse of users
we send older clients a "full-size" node, so that it's impossible for
them to try and walk through a fence or wall that's created in this
fashion. This was tested with a pre-bump client connected against a
server running the new protocol.
These nodes connect to other nodes, and you can select which ones
those are by specifying node names (or group names) in the
connects_to string array:
connects_to = { "group:fence", "default:wood" }
By default, nodes do not connect to anything, allowing you to create
nodes that always have to be paired in order to connect. lua_api.txt
is updated to reflect the extension to the node_box API.
Example lua code needed to generate these nodes can be found here:

This might break some mods, but it is important for all uses of the param2 to
be documented.
This doesn't need a serialisation version or network protocol version change,
as old clients will still work on new servers, and it is bearable to have
new clients getting non rotated plants on old servers.
