I will try and fix that today, for RC1.  K key is undocumented and will be
dropped later, in favour of proper theming, but white screen is bad ...

Toughski titski ... :-)

It's only a tan() function and I use it elsewhere to calculate how to
fit the cubes into the view.  Must encapsulate that some time ... and
there is far tougher maths elsewhere in Kubrick ... ;-)

Being a mathematician by training, though 50 years out of practice,
I tend to favour the generality of staying in one set of co-ordinates
that handles everything ... i.e. 3D, and there is only one rectangle to
draw in "2D".  So thanks, Matthew, for the offer of a patch, but not
this time around if it is all the same to you.  Thanks, too, for all the
insights you have given me into how OpenGL works.

All the best, Ian W.
