• helpers for spatial (anglr/silicate is an attempt, perhaps from a too-general basis)
• illustrations of navigation-customization, it's available but v. few examples (and I can't get it to work) https://stat.ethz.ch/pipermail/r-devel/2015-November/072007.html
• efficient conversion to html (though with use of terrainmeshr maybe ok now) rglwidget - can it be improved (much?)
• thorough helpers for mesh3d textures (WIP https://github.com/hypertidy/textures)
• in-memory textures (i.e. an image for the $texture coords without needing a .png file)
• DONE, rgl 0.106.8 includes mesh3d() a formal class for segments a la mesh3d/shape3d so plot3d() works with lines
  a bit of plot4d() experimentation, animate the device or render frames(or both? for different goals)
• subdivision3d fails to split colours (a minor-ish bug, but what about other material properties)
• more community engagement, push to get rgl on github or gitlab so improve visibility and get PRs rolling
• explicate use of quad reprojection to do a cheap image reprojection without heavy raster warping texture mapping as a raster warper textures#3
