In a nutshell ... I'd like to be able to set the default values for  
properties representing vectors. For example, figure.paperposition  
where we'd like the default to be [0.25, 2.5, 8, 6]. I don't see how  
this can be done. In graphics.h.in I can set each element to the same  
value (all zeros for example), but I don't see how to set the default  
to a vector with differing values.

Then there is the problem that the defaults are set after the  
callbacks are in place, which changes some of the defaults. As you  
point out this can be easily fixed, but I'd think it more proper to  
set the defaults prior to setting up the callbacks.

I'd happy to work on this, but lack the c++ competence to see how.  
Perhaps my ignorance is blinding me to the obvious solution. Is there  
already a method to set the default for a vector of differing values?
