Speed up plotting to MSWindows graphics window
...exe (all this works).
The plot is drawn by R directly to the windows graphic device.
The data is imported from a .csv file (typically around 100MB) to a matrix.
(timestamp, message ID, byte0, byte1, ..., byte7)
I then separate this matrix into several by message ID (dimensions are
in the order of 8cols, 10^6 rows)
The panning is done by redrawing the plots, shifted by a small amount.
So as to view a window of data from a second to a minute long that can
travel the length of the logged data.
My problem is that, the redrawing of the plots whilst panning is too
slow when dealing with this much...
