CMake 3.12 introduces a `...<max>` syntax in the version given to
`cmake_minimum_required` to automatically set policies to NEW up
to that version.  Use it to avoid listing policies explicitly.

The syntax is compatible with older versions of CMake such that they use
the extended version string for the `CMAKE_MINIMUM_REQUIRED_VERSION`
variable (which we don't use) but otherwise ignore it.

Now when jittering is on it uses a shared noise texture
from the renderwindow for all mappers and is 64x64 in size.
This cleans up a lot of code and has a smaller memory footprint
etc.

A bunch of tests included OpenGL2 headers when they didn't
need to, so fixed those.

Other tests need OpenGL2 but are in RenderingVolume so moved
them into RenderingVolumeOpenGL2 where they should be.

Shutting up as it seems to be a buig in cppcheck

This is a novel, threaded, parallel algorithm for 2D Voronoi
tessellation. Currently this is in experimental stage but while work is
continuing the filter is useful as is. Basically the algorithm is
parallelized over tiles (i.e., generating points). It depends on a
locator to retrieve sorted, close points to a generating point,
using these point neighbors to perform repeated clipping to produce
the convex Voronoi tile.
