Hi Bill,

FontForge was having trouble importing the SVG Refinement because the 
symbols were too small and too irregular.  Enlarging the SVG Refinement 
by itself wasn't enough.  With the custom work that Adam Frost and I did 
putting the SVG Refinement together, the SVGs were valid for display, 
but FontForge choked on some weird issues.  This isn't an issue with the 
SVG Refinement, but with the FontForge import.

Luckily, Inkscape is able to understand the SVG Refinement without any 
issues.  A series of conversions later and I have a new SVG set that is 
enlarged and more regular.   The FontForge results will be much better 
with the new SVG set.

The SVG Line conversion has been running for the past 4 hours and the 
hands are almost complete.  No crashing.  A few more hours and I will be 
able to produce an accurate TrueType font.  I am very excited.

Then I need to run the whole conversion a few more times for the filling 
and then for the shadow.  There are a couple of other cleanup issues 
where I'll need to run partial conversions.  I should have all of the 
source images done this week.

After I have the symbol glyphs accurately importing into FontForge, I 
can focus on some of the TrueType properties that deal with alignment 
and other such issues.
