started adding ability to render single frame

I'm not finished, but I want to commit now before I mess with the Visual
Studio 2010 C++ redistributable.  I haven't needed the DirectX SDK until
now because I haven't needed the extensions to DirectX 10 and 11.
DirectX SDK installed, now rendering blue frame!

Yay!  I am rendering a simple window filled with blue by DirectX.
almost rendering, but getting error

The Direct3D shader compilation is failing.  I am committing before I do
a big copy-paste from the tutorial.
fixed it!  Ctrl-C+V bit me in the butt

A copy-paste thing in init_pipeline() resulted in the pixel shader not
being created.  I had copied the line that created the vertex shader to
the line that created pixel shader, but I had failed to change all the
parameters from "vertex" to "pixel".
