Though a sweep of fixing some of the new lints should be done someday.

VTK is not careful about padding in classes in general and prefers
grouping member variables based on their use.

Some classes just need a C++ makeover. Other than that, investigation is
needed (mainly the wrapper tools).

The wrappers cannot handle the syntax.

This causes a lot of unnecessary code churn right now.

VTK is rife with short identifiers. Not something to change today.

VTK's API would be torn apart trying to obey this. Suppress it instead.

Qt6 turns on C++17 on us and exposes this lint.

This function is C++14 only, so it should not be suggested by
`clang-tidy`.
