* Rewrite shadow filtering for the new distortion
* Calculate penumbra radius using a single sample
* Avoid peter-panning effect due to filtering of short shadows
* Add adaptive filter quality for soft shadows
* Avoid sharp shadows on surfaces without normals (e.g. plants)
* Increase default and maximum soft shadow radius
* Make line numbers in shader errors match the code
The logging streams now do almost no work when there is no output target for them.
For example, if LL_VERBOSE has no output targets, then `verbosestream << x` will return a StreamProxy with a null target. Any further `<<` operations applied to it will do nothing.
The dynamic shadows are yet not in the desired state to justify the
inclusion into version 5.5.0. A stable release is long overdue, hence
this allows fixes to continue in 5.6.0-dev to finally release an
acceptable version of the dynamic shadows feature.
Reverting this commit is highly recommended to proceed in development.
Reduces stutter and freezes when playing.
* Maintains double SM and SM Color textures
* Light frustum update triggers incremental generation of shadow map into secondary 'future' textures.
* Every incremental update renders a portion of the shadow draw list (split equally).
* After defined number of frames (currently, 4), 'future' and 'current' textures are swapped, and DirectionalLight 'commits' the new frustum to use when rendering shadows on screen.

This completely removes any mention of the software and D3D drivers from MT, preventing the user from accidentally attempting to use them. Users who need a software renderer should be asked to install Mesa drivers which offer superior fidelity and performance over the 'burningsvideo' driver.
If enabled in minetest.conf, provides colored, clickable (middle-mouse or ctrl-left-mouse) weblinks in chat output, to open the OS' default web browser.
This only works when shaders are enabled.
The centroid varying avoids that the textures (which repeat themselves out of bounds) are sampled out of bounds in MSAA.
If MSAA (called FSAA in minetest) is disabled, the centroid keyword does nothing.
Erase all traces of normal "generation" from fragment shaders
Remove the "feature" from the engine and default config
Remove any leftover documentation of it
