Hi,

I just pushed a series of patches for gEDA/gaf.  While most are small 
improvements and bugfixes, there's one change that may be worth extra 
mention:

Object data is now validated and normalized when it enters a revision 
object.  Validation means that an attribute can only hold a value which is 
valid for this kind of attribute in order for the operation to succeed; 
e.g., an angle can only be set to 0, 90, 180, or 270.  Normalization means 
that unused fields are stored as a valid default; e.g., if an object has a 
hatched fill, retrieving the second angle or pitch value always yields 
zero.

In theory, this shouldn't affect the behavior of gEDA/gaf in any way. 
However, there were several places in the code which relied on storing 
technically invalid values in some fields; most importantly, unused fields 
were set to -1 internally.  I believe I fixed all relevant places in the 
code, and the tests run fine, but I'd be grateful if you could run the 
current netlister against your designs anyway and report any unexpected 
errors.

Roland
