in CVS: fixed in all fonts
open paths
intersecting paths
outermost not clockwise
flipped references
also checked points outside glyph

To go farther: need to also fix mixed references and contours.
(badly affects hinting in TrueType)

Note: Most of the problems were plainly mistakes, or problems that cropped up after some transformation of the glyph. Others seem to be the result of freehand drawing or scanning.

FontForge "Find Problems" function reports many cases of

Open Paths
Intersecting Paths
Outermost paths not clockwise
Missing extrema

Open paths is just wrong and and likely to cause display problems. TrueType insists on the non-intersection and clockwise properties. Missing extrema can cause hinting problems.

In CVS, fixed all cases of the first three, but only got through the Arabic range with Missing Extrema.
