Semantics and dictionaries aside, I'm making the observation that in 
GUIs border and bevel are typically matching the definitions I 
provided. My vote is to keep them separate. I see several paths to 
follow:

1) border is a widget. If one must be a proxy then border should be a 
proxy for bevel wherein the color for top-left is identical to 
bottom-right. The downside to being a proxy is that a bevel probably 
takes nominally longer to draw.

2) border and bevel are both attributes of _all_ widgets.

3) implementing CSS 1's box properties: 
http://www.w3.org/TR/CSS1#box-properties, perhaps with the caveat that 
all length's are pixel based. (for now?) The inset and outset values 
for the border-style property being inner and outer bevels.

I haven't been following your hard work as closely as I should be, but 
I lean heavily towards option 3 and fallback on 2. Then again I'm not 
the one doing the work. :\
