when using typescript with strict on, i see these issues that are due to .d.ts incompleteness.

Error: node\_modules/@kitware/vtk.js/Common/Core/ScalarsToColors.d.ts:137:19 - error TS7006: Parameter ‘scalars’ implicitly has an ‘any’ type.

137 areScalarsOpaque(scalars, colorMode, componentIn): boolean;  
~~~~~~~

When typescript strictness is off ( “strict”: false in tsconfig.json), the issue does not  
appear.  
These two are the only occurrences i see.
