[Cuis-dev] Color Editor adds alpha-transparency slider

[ken.dickey at whidbey.com]

Greetings all,

I had a need to set transparency so thought best to add the facility to 
the Color Editor.

Transparency really is unrelated to other, true color features, so I 
wanted to have a separate control affordance.

It makes sense to me to distinguish the non-alpha focus color from the 
same color with transparency added by adding the new, third, color 
swatch.

Now that there are 3 color swatches, I tried to minimize confusion by 
using the balloon help.

One thing I find this helpful for is drag 'n drop color changing for 
vector shape morphs.  Solid color for border, same color with alpha for 
fill.

Let me know how this feature addition and UI change work for you!
