This patch replaces the statement in the README about a build dependency of the
minetest binary on the package “build-essential” with a corresponding statement
about build dependencies on the three packages “g++”, “make”, and “libc6-dev”.
Though often used as a shorthand, “build-essential” is not a package used to
install packages that are essential for building software – “build-essential”
depends on packages that are essential for building Debian packages. Therefore,
the dependency on “build-essential” implies a dependency on a lot of packages that
are not actually necessary to build minetest (e.g. the Perl programming language).
Low-disruption first step towards removing the hardcoded cave liquid
code. Since MT 5.0.0 cave liquids can be defined and located by
biome definitions instead.
In games that do not yet use biome definitions to define and locate
cave liquids (MTGame does), lava will now appear below
y = water_level - 256 instead of below 'lava depth' (usually y = -256).
Therefore no change in most mapgens if using the default 'lava depth'.
The upstream JsonCpp project has renamed the `json/features.h` file to
`json/json_features.h`. This patch fixes the JsonCpp installation search
by looking for `json/allocator.h` which has not been renamed on newer
versions of JsonCpp.

Tunnels: Completely disable generation when 'cave width' >= 10.0 (#9093)
Previously, the only way to disable the 3D noise tunnels was to set
'cave width' > 1.0, however doing so did not disable the very intensive
noise calculations or the generation loop.
All the other types of cave generation (randomwalk caves, caverns)
can already be independently and completely disabled.
This feature is now needed more because the small randomwalk caves are
now available for use as an alternative to the 3D noise tunnels.

Randomwalk caves: Add parameters for number, proportion flooded. Allow small caves (#8928)
Add mapgen parameters to set the range of the random number of
randomwalk caves per mapchunk, and to set the proportion that are
flooded with liquids.
Default values are, for now, unchanged from the previous hardcoded
values.
Add parameters to allow small randomwalk caves
Disabled by default for now as they have never been present in the
non-mgv6 mapgens.

Improve light curve parameter limits and documentation (#9054)
Revert gamma upper limit to 3.0 because that was raised based on
a misunderstanding and had no benefit. A sane upper limit is
needed as players on a competitive server tend to use the maximum.
Set gamma lower limit to 0.33 for consistency with 3.0.
Set sane limits on alpha, beta, boost and enforce these in code
to limit values entered in minetest.conf and to avoid easy cheating
by editing settingtypes.txt.
Improve documentation and 'readable' setting names.
Clarify that gamma does not significantly affect natural night light.
light.cpp: Various codestyle and comment improvements.

Fix rotate_node to return the correct itemstack.
All on_* hooks that return an itemstack are NOT guaranteed to
modify and return the original stack. We cannot count on the
behavior of the existing builtin definitions not to be overridden
by game/mod logic.

Randomwalk caves: Reduce 'insure' value from 10 to 2 (#9035)
This value reduces how far randomwalk caves can extend into the
mapchunk padding, to avoid 'out of voxelmanip' cave nodes which cause
flattened cave walls.
Testing shows that a value of 2 (instead of 10) is enough to make
'out of area' nodes extremely rare.
Reducing this value results in a higher chance of overlap and
connection with caves of neighbour mapchunks.

2. Pass animation timer to fragment shader. C++ code is already there, just wasn't declared in the shader
3. Delay animation timer wrap-around (from 100s to about 16 minutes)

Improve undersampling settings
The setting now accepts values between 1 and 8 in the
Advanced Settings menu.
Values 0 and 1 now behave the same way (setting it to 1 won't
disable MSAA anymore), so there's no need to expose 0 as a value.
