[Blindmath] Updated version of my SVGDraw01 SWT/SVG based drawingprogram

Sun Sep 4 01:40:01 UTC 2011

CsvTest01.csv is an inverted parabola that begins at the upper-left corner
of the page. Moving from left to right, the slope continually increases with
maximum slope at the right end.

CsvTest02.csv is a parabola that begins at 0,0 and increases in slope moving
from left to right.

CsvTest03.txt is the same as CsvTest02.csv
