Distribute shadow map update over multiple frames to reduce stutter (#11422) 
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.

Add smooth light-shadow transition at noon (#11430) 
Node faces with normals pointing East/West (+X/-X) will transition between light
and shadow at noon. This code makes the transition smooth.

Improve shadow rendering with non-default camera FOV (#11385) 
* Adjust minimum filter radius for perspective

* Expand shadow frustum when camera FOV changes, reuse FOV distance adjustment from numeric.cpp

* Read shadow_soft_radius setting as float

* Use adaptive filter radius to accomodate for PSM distortion

* Adjust filter radius for texture resolution

Cleanup shader generation code (#10663) 
Shader generation is a mess. This commit cleans some parts up, including dropping remains of HLSL support which was never actually implemented.

Fix MSAA stripes (#9247) 
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.

Simple shader fixes. (#8991) 
1. Pass current camera offset to shader, so shader have access to the global coordinates
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)

Require 'waving = 3' in a nodedef to apply the liquid waving shader (#8418) 
Makes the liquid waving shader per-nodedef like waving leaves/plants,
instead of being applied to all liquids.
Like the waving leaves/plants shaders, the liquid waving shader can
also be applied to meshes and nodeboxes.

Derived from a PR by t0ny2.
