Remove section on good sizes from NOTES

It's been pretty much obsolete since 002.002 when I adjusted the
diagonal stroke thickness.

-Good bitmap sizes for Bedstead fulfill two characteristics:
-
-1: An integer number of output pixels per Bedstead pixel (so
-horizontal and vertical lines work).
-
-2: Edges of diagonals don't pass through pixel centres (so no doubt
-whether any pixel is in or out).
-
-The first requires that the height be 10n for integer n.
-
-The second requires that the height _not_ be 40n for integer n.
-
-So good sizes are 10, 20, 30, 50, 60, 70, 90, 100, etc.
-
-The best sizes would be those where the area of a (long) diagonal line
-is correct.  The outline version has an area of 1 - (0.25^2) + (0.75^2) =
-1.5/pixel.  Others:
-
-size | area/diagonal pixel
------|--------------------
-10   | 1
-20   | 1+1/2 = 1.5
-30   | 1+6/9 = 1.67
-50   | 1+10/25 = 1.4
-60   | 1+18/36 = 1.5
-70   | 1+28/49 = 1.57
-90   | 1+36/81 = 1.44
-100  | 1+50/100 = 1.5
-
-So the _very_ best sizes are 20, 60, 100, etc.  90 and 50 are pretty
-good because they're between √2 and 1.5.
