Switch between outline and data subset mode on the graphics card #310

This makes the change quasi-instantaneous instead of quite slow.

Fixes #304 Fixes #305

It seems that OpenGL on Travis can't deal with the complexity of the fragment shader, so instead we could dynamically swap the vertex code on-the-fly using:

viewer._vispy_widget._multivol.view_program.frag = frag

This works reasonably fast.
