Rendering plugin

Description
Here is a small plugin to render images with a given DPI.
The "Ray" button raytraces, and the "Draw" button just draws the image without raytracing (a fast way to see that the height/width look good).
It warns you not to have the plugin window on top of your main PyMOL window when you click "Ray". That doesn't seem to be necessary anymore, at least on my MacBook Pro.
The functionality is also available as a script (see my .pymolrc here).
Here's the imperial version. The metric version follows.
