Allow the screen bounds difference in CON showview/-unbiased to be less than 2.

This requires one tweak in drawrooms' umost/dmost setup to prevent oob access.
Specifically, a coordinate difference of 0 is allowed.  In the classic renderer,
this would mean a one-pixel (real screen coords) height or width.  In Polymost,
it would currently mean a one-pixel height and zero-pixel width, but this might
be subject to change.

New CON command 'showviewunbiased', mapping the screen coords w/o round-to-0 bias.

The showview command transforms the 320-based screen bound coordinates to the real
screen bounds like xreal = (x*xdim)/320, which shows a bias towards zero: for
example, for a 1680 screen width, the maximum permissible value 319 is mapped to
round_to_zero((319*1680)/320) == 1674.  (The rounding is implicit in the integer
division).  This makes it impossible for a view to cover the whole screen with any
other resolution than 320x200.  The new command transforms the bounds like
xreal = (x*(xdim-1))/319, which would map 319 to 1679 in the preceding example.
