Xorg's XIWarpPointer doesn't support multi-head display while
XWarpPointer does.
Revert since this is a known TODO in Xorg and setting a custom
xinput matrix seems not to be used often.
Resolves T50383
This disables touch gesture recognition in Blender, avoiding any initial delay
when drawing with grease pencil, texture paint, etc.

This change brings back old original logic which was checking
whether worker threads do fit into an active CPU group. But
it does it a bit smarter now and is also checking affinity
within that group. This way Cycles will use all threads on a
Threadripper2 CPU if it's set to automatic number of threads,
but on another hand will not change affinity if user requested
16 threads and changed Blender affinity.
Tweaked scheduling so it survives this situation by scattering
"extra" threads uniformly over all the NUMA nodes.
There are still tweaks possible to make some specific hardware
configurations work better.
Please always build tests when messing with build system/libs, am tired
of fixing that kind of issues...
Also, that fix is probably not working for standalone, no idea where's
the numaapi lib then, but committing since I need a building blender
here (with the tests, yes).
The issue was introduced by a Threadripper2 commit back in
ce927e15e0. This boils down to threads inheriting affinity
from the parent thread. It is a question how this slipped
through the review (we definitely run benchmark round).
Quick fix could have been to always set CPU group affinity
in Cycles, and it would work for Windows. On other platforms
we did not have CPU groups API finished.
Ended up making Cycles aware of NUMA topology, so now we
bound threads to a specific NUMA node. This required adding
an external dependency to Cycles, but made some code there
shorter.
Previously we would try to guess what the main tablet device is, but this is
error prone. Now we keep a list of X11 devices and try to match events to
them. On the Blender side there are still some limitations in regards to using
multiple devices at the same time, but this should improve things already.
Fixes T59645.
The key indices were wrong: need to offset curve key index
by first curve key index. Also corrected calculation of the
interpolation step.
Annoyingly, can not reproduce this on a simple file, need
production rig. For the possible future look the following
file from Spring was used: 03_005_A.lighting.debug.blend
There are some changes in API of OpenImageIO, but those are quite
simple to keep working with older and newer library versions.

It used to be used for some sort of ignoring automatically
generated bump nodes. But nowadays it causes one of the shaders
in Classroom demo file to be compiled wrong.
This is unfortunate, but the number of bugs in this configuration
keeps growing, and almost all of them are caused by bug in OpenCL
compiler.
The compiler is not likely to be fixed, since Apple declared OpenCL
deprecated.
This evil commit is aimed to keep officially supported features
of Blender in a good working and stable state.
