Arbitrary meshes instead of quads

[lpdon]

First of all, thanks for the plugin. It helped me out a lot in some situations in the past. For a task I needed basically the same thing, but wanted arbitrary meshes instead of quads. I used your repo and hacked a quick&dirty solution. If someone wants dynamic textures in meshes for rviz, this may be helpful as a starter: https://github.com/lpdon/rviz_textured_meshes
