The crash was caused by allocating an uninitialized amount of memory.
This fix initializes a bunch of variables that could cause the error.
It should be possible to also fix this in the function that actually uses
the uninitialized memory, but that could cause unknown consequences
that are a bit too risky for 3.0. Just initializing some variables should
be safe though. For more details see D13369.

This is a code refactor in preparation of supporting canvas
compositing. See {D12466}.
No functional changes, all canvases are at (0,0) position matching
tiled implementation.

Adds full frame implementation to this node operations.
No functional changes.
2.3x faster than tiled fallback on average.

The mixing function was designed to give correct results for Mix values of
-1, 0, and +1, but the behavior between these points was not linear. This is
unavoidable, because the function depends on both Mix and Mix^2 (by
multiplying value and mf) so they could not cancel out completely.
The new formula simply calculates the weighted sum without trying to invent
a smooth function.
Value for MixGlareOperation is now passed directly without scaling because
it is then easier to use.
Note that the previous formula performed max() twice for both input image
and the result, now there is just one max() per channel because the glare
input can't be negative.

This removes a lot of unnecessary code that is generated by
the compiler automatically.
In very few cases, a defaulted destructor in a .cc file is
still necessary, because of forward declarations in the header.
I removed some defaulted virtual destructors, because they are not
necessary, when the parent class has a virtual destructor already.
Defaulted constructors are only necessary when there is another
constructor, but the class should still be default constructible.
