Summary: Eyedrop doesn't seems to work porperly

Initial Comment:
Using svn 1849

For example. Over a feathered region it doesn't read properly the alpha value. 
Sometimes it read 100% sometimes it reads 0%. But for a feathered circle yes.

For Radial Blurs it seems not to work.
For Blur it works like for feather: a 100% 0% thing.

For Mandelbrot's and Julia it seems to work.
For gradient I still so confused. If there is not transparency it works fine. 
But if there is transparency it seems to fail with the RGB.

"eyedropper doesn't work with straight blends"

draw two overlapping circles
set the top one to be 'straight' blended, with an amount of 0.5

the overlapping region will be opaque, but the other parts of the 2
circles
will be semi-transparent.

point to them, and look at the 'A' field in the 'Info' panel. it shows
100% in one of the two semi-transparent areas.

this has since been fixed for circles, rectangles and 'shapes'.  it's
possible that some layers still have the problem.

"get_color() in layer_shape is ugly for feathered edges"

See http://dooglus.rincevent.net/random/region-twirl.sifz for example -
each pixel from get_color() is either inside or outside - there's nothing
between in the feathered region.

get_color() uses the single-pixel Blur operator() method rather than the
surface version.  It gives us a pixel that's either inside or outside the
blurred shape.
