Gawain: Reduce shader interface bucket size

Tried 101 but it gives colisions.
I think 257 is enough now that we dont have thousands of uniforms.
This gives some noticeable performance improvement.
Could be refined further.

Gawain: Add UBOs to shader interface.

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

disabling fractions and enabling moving obstacles again

fractions do not support moving obstacles right now. also, fractions combined with obstacles results in particle leak (likely because of inaccuracies at fluid/obs border when repeatedly subtracting from phi grid - sdf not preserved)

Merge branch 'master' into blender28

Cleanup: Math lib naming (use v3 suffix)

Merge branch 'id_override_static' into asset-engine

Sequencer: Cleanup, use more BLI utilities where possible

Merge branch 'master' into id_override_static

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.

Vertex Paint: use brush front-face setting

Follow sculpt mode more closely by using the brush front-face option.

Sculpt: use tube falloff when calculating normals

Also apply 2D clamping for other tools when the option is set.

Sculpt: clamp normal to plane w/ projected falloff

Allows for editing outlines w/o pushing geometry towards/away from
the view.
