bf_intern_mantaflow lacked the `-DOPENVDB_STATICLIB` define
causing it to dynamically import openvdb, linked against
our static libs a happy time was not had by the linker.
Cache files are currently loaded via the Manta Python API. With very big caches this can slow down the viewport playback. Especially smoke simulations, which just load grids and no meshes, can suffer from this. This fix solves this problem by directly loading the cache files from disk (no Python). This fix has been in the works for some time. The developer of this patch is ready to handle any potential fall-out of this patch quickly.
Not sure when this happened but apparently the lower bar is now windows 7 [1]
This patch bumps to API version to 0x0601 (Win7) and cleans up any uses that
worked around the globally set API version.

To determine the albedo pass, Cycles currently follows the path until a predominantly
diffuse-ish material is hit and then takes the albedo there.
This works fine for normal mirrors, but as it completely ignores the color of the bounces
before that diffuse-ish material, it also means that any textures that are applied to the
specular-ish BSDFs won't affect the albedo pass at all.
Therefore, this patch changes that behaviour so that Cycles also keeps track of the
throughput of all specular-ish closures along the path so far and includes that in
the albedo pass.
This fixes part of the issue described in T73043. However, since it has an effect on the
albedo pass in most scenes, it could cause cause regressions, which is why I'm uploading
it as a patch instead of just committing as a fix.

Lacunarity parameter determines scaling of subsequent octaves in fractal
noises. For example, Noise node have this scaling hardcoded to 2.0. Each
octave have twice bigger scale than previous one, resulting in finer details.
By design fractal noises that generate octaves with same seed should not
have Lacunarity set to 1.0, since then it just stacks up identical noises.

Specifically, this happened when automatically hiding and showing of the
menu bar and dock was enabled in the system preferences.

Some code was removed to avoid storing the combined pass when viewport
rendering other passes. But we can keep this by default, Blender overrides
the list of passes entirely.
This commit cleans up the flow emission code (i.e. the code that determines where flow is generated). It also addresses an issue with initial velocities.
Related issues (that might be fixed through this commit) are: T73422, T72949
This is done with two-finger double tap on trackpads, and is usually used to
zoom into an element under the cursor.
It can now be used for toggling local view in the 3D viewport.

This is a step towards Wayland and headless rendering support, using EGL
instead of GLX. The EGL backend is not enabled by default, it can be tested
using WITH_GL_EGL=ON.
