Reverts rBb9ae517794765d6a1660 and fixes the issue properly. Old fix could cause
NULL to be passed to functions that expect all arguments to be non-NULL.
The idea is to separate the most common case from symmetrical frustum. And to make a simple but efficient calculation.
The new radius is usually 98% the size of the radius size of the asymmetric solution.
Thanks to @fclem for reviewing the patch on IRC
Also get rid of the static var and initialization.
This enables the user to see the progress on the info header.
Closing blender or reading a file also kill the job which is good.
Unfortunatly, this job cannot be interrupt by users directly. We could make it interruptible but we need a way to resume the compilation.
In the gpus like `AMD Radeon HD 7570M` and `Intel(R) HD Graphics 4000` this solution improves performance a hundreds or even thousands of times depending on the resolution.

Vertex group remapping utility function,
now shared between object join and array modifier cap-ends.
Weights which don't exist are removed.

Main purpose is to make it possible to cover FPS detection with regression test.
But it might also be handy for some other scripters.
Thanks Campbell for review!
The issue was happening with fast Gaussian blur, and caused by NaN value pixels
in the input buffer.
Now made it so Map Range output does not produce NaN, by returning arbitrary
value of 0. Still better than NaN!
Previous fix for T53430 caused T54200.
The edge case for soft & hard cuts weren't working,
where the strip used start/end-still & the frame was placed exactly on
the start/end of of the sequence content.
T54200 fixed the end-still case but broke hard-cuts for all other cases.
This fixes the case for soft/hard cuts with/without start/end-still.
I keep reading that texture painting is not working yet. However it is fully
working. We even have a "Full Shading" option in the viewport display panel.
Clay/EEVEE still need their UI figured out. But the context itself is doing
its part after this patch, and at least for Cycles it's working like 2.79.
