Rewrite some in-hand rendering code

- Fix missing shader for printout render type
 - Use current buffer provider for pocket computers rather than the
   tesselator. This requires us to use a non-depth-writing terminal +
   depth blocker, as otherwise one gets z-fighting.
 - Thus refactor some of the shaders to be terminal wide, not just for
   monitors.

Fixes #894
