Arguments for Report Generation:

`-noverb`			Verbose Mode Off.
`-verb`			Verbose Mode On.

Notes on Graphics Coordinates:
X Coord Increases from Left to Right.
Y Coord Increases from Top to Bottom.
Units:
No Label = Pixels, Absolute Coordinate.
pix = Pixels, Absolute Coordinate.
in = Inches, Relative to Cell.
cm = Centimeter, Relative to Cell.
mm = Millimeter, Relative to Cell.
c1 = Char Size of Small Font, Relative to Cell.
c2 = Char Size of Big Font, Relative to Cell.
% = Percent of Screen, Relative to Cell.
Display Region Aspect Ratios:
[ppm|Hz|Pts|%]/[Pix|In|cm|mm|c1|c2|%]
