Fix incorrect MIS with principled BSDF and specular roughness 0.

[cmake] Add minimum python version check to cmake to prevent later build errors.

Code cleanup: simplify cmake kernel install.

Cycles: CUDA bicubic and tricubic texture interpolation support.

While cubic interpolation is quite expensive on the CPU compared to linear
interpolation, the difference on the GPU is quite small.

Code refactor: make texture code more consistent between devices.

* Use common TextureInfo struct for all devices, except CUDA fermi.
* Move image sampling code to kernels/*/kernel_*_image.h files.
* Use arrays for data textures on Fermi too, so device_vector<Struct> works.

Actually force accumulate mode for the Smear brush in weight/vertex paint.

Just removing the checkbox from UI isn't enough for proper behavior.

Make weight paint blur thread safe, and fix smear ignoring mirror.

Instead of trying to be clever with swaps and lazy updating the weight
data, simply recalculate one single array. To improve performance, use
threading for that.

Cycles: Fix possible race condition when generating Beckmann table

Two issues here:

- Checking table size to be non-zero is not a proper way to go here. This is
because we first resize the table and then fill it in. So it was possible that
non-initialized table was used.

Trickery with using temporary memory and then doing table.swap() might work,
but we can not guarantee that table size will be set after the data pointer.

- Mutex guard was useless, because every thread was using own mutex. Need to
make mutex guard static so all threads are using same mutex.

Cycles: Cleanup, indendation

Fix T53012: Shadow catcher creates artifacts on contact area

The issue was caused by light sample being evaluated to nan at some point.
This is root of the cause which is to be fixed, but is very hard to trace down
especially via ssh (the issue only happens on AVX2 release build). Will give it
a closer look when back to my AVX2 machine.

For until then this is a good check to have anyway, it corresponds to what's
happening in regular radiance sum.

Cycles: Cleanup, indentation and wrapping

Cleanup: Math lib naming (use v3 suffix)

Sequencer: Cleanup, use more BLI utilities where possible

Sequencer: Use BLI math functions where possible

Sequencer: Avoid re-calculation index offset multiple times

Sequencer: Use funciton instead of macr oto avoid argument re-evaluation

Fix T52940: VSE Glow Effect Strip on transparent images has no blur

Error in falloff_angle range in last commit

Vertex Paint: move normal falloff into the brush

All related settings are already in the brush,
so it's inconvenient to switch panels to change this one option.

Vertex Paint: use view normal w/ 2D falloff

When projecting to the view, cull faces pointing
away from the view normal.
