The currently established convention uses `NS` for "translation no-ops", i.e., it will be collected by a string-collecting utility but not be translated by Luanti at this place.
We don't want to mislead modders with this example into using `NS` for plural forms instead, breaking with the established convention and making use of automated tools harder.

We are being lax here, but the glTF specification just requires that "when the weights are stored using float component type, their linear sum SHOULD be as close as reasonably possible to 1.0 for a given vertex"
In particular weights > 1 and weight sums well below or above 1 can be observed in models exported by Blender if they aren't manually normalized.
These fail the glTF validator but Irrlicht normalizes weights itself so we can support them just fine.
The docs have been updated to recommend normalizing weights (as well as documenting the status of interpolation support).
Weights < 0, most of them close to 0, also occur. Consistent with Irrlicht, we ignore them, but we also raise a warning.
This lets modders avoid alpha blending rendering bugs as well as potential (future) performance issues.
The appropriate blend modes are also used for node dig particles.

New parameter 'content padding'. When specified, the scrollbar
max value is calculated automatically. This aims to reduce manual
calculation functions.
This improves texture pack compatibility. Masks are expected to be of the same
size as the base texture. This change upscales the smaller texture if needed.
The behaviour is now the same as a.png^b.png and a.png^[overlay:b.png (to mention a few).
This PR adds a variety of effects to enhance the visual experience.
"soft" clouds look
Tinted shadows
Crude water reflections (sky and sun) and waves
Translucent foliage
Node specular highlights
Adjusted fog color (more saturated where the fog is lighter)
Minor changes to volumetric lighting (crudely simulates the effect of depth)
