[Gimp-developer] Show clipped and out of gamut colors using blinking colors

[Elle Stone <ellestone ninedegreesbelow com>]

Hi All,

It would be really nice to be able to click a button or have a view 
module option that would indicate clipped colors by coloring them in 
some way (perhaps black for shadows, white for highlights), with an 
option to make these pixels blink.

UFRaw, darktable, RawTherapee, PhotoFlow all provide this functionality 
via buttons on a bar below the image. In GIMP, maybe the status bar 
would be a good location.

This topic was briefly mentioned on the gimp dev list back in April 
2015. There are two open bug reports. Also the question came up today on 
the pixls.us forum:

- there was a suggestion that this functionality already exists, but if 
it does, I can't find it :) .

Best,
Elle
