requested to merge florian360/vtk:FixLagrangePointParametricCoordinatesReleaseParaview into paraview/release
Backport to release paraview !6851 (merged) and !6929 (merged)
@tjcorona sorry for the duplicated work, the last common commit between the master, release and release/paraview branches was too far away to do a common single MR.
