My current thought about window size is kind of the opposite of yours,
namely, that the device will set the size when it is 'opened'.
This handles both X Windows, where the size is set dynamically by the
user, and ordinary devices, whose size is known in advance.
But maybe an arrangement allowing either would be best.

Regarding draw_line, the new documentation with 1.3 will specify that
it includes (x0,y0), but not (x1,y1): however, if y1 < y0, you must swap
the endpoints first.  I'm trying to take the same position on these issues
as both X and Display PostScript do, namely, to consistently use half-open
ranges that include the lower but not the upper endpoint.
