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.
Instead of creating a new instancing shading group without attrib, we now have instancing calls. The benefits is that they can be culled.
They can be used in conjuction with the standard and generate calls but shader must support it (which is generally not the case).
We store a pointer to the actual count so that the number can be tweaked between redraw.
This will makes multi layer rendering more efficient.
Introduced explicit ID property node for driers in depsgraph,
so it is clear what is the input for driver, and what is the
output.
This also solved relations builder throwing lots of errors
due to ID property not being found.
It was too tricky to know ahead of time if an object would still
be visible in the new window/workspace/scene/layer combination,
especially since other windows may share some of these data-blocks.
So store the context, make the change, then check if the object is
still visible, freeing mode data of it's not.
It was possible to have relations like A -> B -> C -> A (import thing is
that no other operations points into this cluster) which were not detected
or reported by dependency cycle solver.
Now this is solved by ensuring we don't leave unvisited nodes behind.
This is probably a better way to handle it: instead of totally
discarding scaling of non-free axes, keep the ratio between them.
Basically the logic of the constraint is now that it rescales the
object uniformly in the non-free axis plane in order to force the
total volume change to the desired value.
Note that this code will likely be generalized,
currently each new case is a little different though
so it's too early to move them into general functions.
This (now removed code) calls gl_Vertex deprecated draws. It was doing
background drawing (color gradient, flat background) which is not used
by any engine.
