update:

-i now use an internal bitmap so i only need to do
 pattern { object text }} once. (MUTCH faster)
-i changed the blurring macro into something that works
 better with thin objects.
 full source (except the font file)

-in the image below you can see that it works reasonably
 well with pixel maps (blurred in external program).

Q:
What are the 2 extra patterns ?
-i have only one light source
-i removed phong, etc.
-it also appears when i take a single sample (no blur)
-the offset is much bigger than the used blur radius.

any idea what it is ?
