Thanks for that explanation.

Have you played around with the existing noise functions available as 
part of SVG filters?  You can get some of these effects.  [Here are 
some demos I put together of paper/wood 
textures](http://codepen.io/AmeliaBR/pen/IxiCs?editors=1100).

one where the texture has been applied on a multi-color checkerboard 
pattern](https://cloud.githubusercontent.com/assets/9876129/18233416/20ee7856-72a4-11e6-9bb4-282f2aa99807.png)

The main limitation right now is performance: because SVG filters are 
applied as manipulations of the rendered bitmap version of the shape, 
any change to the underlying shape or its position causes the entire 
filter (including noise functions) to be re-calculated.  So noise 
filters + animation are a big problem for performance.
