[PATCH 2.0.14] graphing tests using too large rectangles

[Ilya Zakharevich <ilya@math.ohio-state.edu>]

Graphing tests assume that the size of the plotting device is 1000 or
more.  This is false with gnuplot graphic on X-less system (such as
the telnet session).  The following patch fixes it:

We subtract 11 to compensate for plotdraw([0,10,10]) later in the
tests.  The policy in absense of shifts should be subtracting 1.  It
would be nice if it were documented too.

Enjoy,
Ilya
