Removed "wontfix" TODOs.

* Calling *Mesh::draw() with parameter to start on arbitrary vertex
   index might give users more freedom than they want to have (e.g.
   lines rendered where gaps should be, broken triangle strips...).
 * Single-precision floats have meaningful precision of ~6 decimal
   places, everything after that would be random garbage anyway, so we
   don't need anything "more precise" for icosphere.
 * Texture1D can have only one target and it can be used as framebuffer
   target.
