HID originated partly because pcb's screen and board coords were
thoroughly mixed together in the code, and very difficult to keep
straight.  So now, core ALWAYS uses board coords, and each HID
converts it to whatever "screen" it's using.  Much more sane,
especially when you get into tab-based flipping (multi ways), board
rotations, and postscript's auto-mirror flag.
