ok, 4:21 n the morning...
I just could run gimp 1.3.19 now. 

I don't know how many of these changes came in after 1.3.19, but  
I can only see 2 modes on the tools options.

I am feeling sleepy, and  I could not follow the guidelines below . It 
seens me that the edit mode is not there at all. I will try to build 
the gimp from HEAD tomorrow (I sometimes have problens with this, but 
I am interested enough in the vector tool to help out. So, if  I 
cannot build it, expect me on #gimp looking for some help)

I hope you are willing to change some of these key strokes. I remember 
being able to iamgine something that would make more sense, while 
awake - so I will write more on later. Now I can only note that the 
behavior of the SHIFT key on the simetry of Handles should not toggle 
like that, and IMO should be more consistent. But I will have more to 
say on the keys once I get all the functionality you list bellow.

The ability of changing a segment curvature by draging a randon point 
of  it is quite amazing, rest assured.

As for teh future plans, inr egards to import and export to other file 
formats, There is Python code from both Sven, and another 
implementation by me to export bezier paths to SVG. There is also 
some python code of mine to export them to Postscript and POV-Ray 
sphere sweeps.
(http://hopey.nervo.org/~gwidion/gimp , Sven's code seens to float up 
somewhere in the Tools directory, and I am not certain if it moves to 
anywhere that makes sense when installing) . Needless to say, there 
is no code to read any of these back.

If you feel like python will not be universal enough in Gimp installs, 
I can rewrite some of my scripts in C.

So far, expect me to write more about vectors tomorrow.
I will get some sleep now.
