[pdal] decimation-visualization

[Chris Foster]

If you're looking for a flexible debugging tool, you might also be
interested in my pet project:

https://github.com/c42f/displaz

It's got support for .las and .laz, but also has a .ply variant to
visualize arbitrary attributes on the points.  It's desktop rather
than web based (not fully buzzword compliant!), but on the upside it's
fairly good at displaying reasonably large point clouds; a few hundred
million points are not a problem.

I did add initial support for using pdal as a reader backend a while
ago,  but I think both projects have changed so much by now that it's
unlikely to work anymore.  I'd like to update it to make it work
again, I just haven't had time to do so yet.

Cheers,
~Chris
