As an experiment, I'm trying to duplicate a sample InDesign document with
ConTeXt.  I'm getting the overall layout (though my image positions need
tweaking), but I'm having some problems with the fonts.

I'm following the examples in
http://www.pragma-ade.com/general/manuals/showfont.pdf , but I haven't seen
the \switchtotypeface operator documented anywhere else.  I'm on a Windows 7
machine, with minimals installed.  I'm trying to use some of the system
fonts (Minion, Impact, Myriad), but all I seem to get is CMR.

Also, the line spacing on the paragraph at the top of the second page seems
very weird.  It's an address, and the bottom line is much too high relative
to the spacing of the other lines.

Here's the file:
