[Shotwell] Red eyes zoom - suggestion

While it's good to have zoom, red eyes a lot of the time are NOT round due to eylids. So the tool as is is frustrating to use. Also, it`s annoying and slow to have to select each eye separately.
Currently, the red eye zoom expects to remove the red from the entire area that is denoted by the circle created with the tool.
This is incorrect behaviour.
The red eye tool should be smart enough to only apply the correction to the area within the denoted circle that is actually RED. This is quite simple to do. Simply make an irregular mask based on a red filter. Once that is done, take the original image section corresponding to the new mask (a subset of the denoted circular section), and correct the redness. This makes it quite a lot easier to fix all manner of irregular shapes. It removes any red from a subsection of the image (leaving other valid red areas... jackets/scarves true). You really only need to define a range of colour which is considered red to create the irregular mask.
This also paves the way to selecting both eyes at the same time, or even using a square area... it will be irrelevant what the shape the user denotes since only the red areas within that shape will be modified. All red-eye tools I have used before did this at least.
In addition, this paves the way for enhancing this to autocorrect red-eye for the entire picture, with one click and not specifying an area at all... the picture is the area that the algorithm would be applied to. Since this will possibly cause more collisions with other valid red ares, it would likely need to be enhanced. You simply need to marry the above to eitherto
a) face detection to make changes only to anything red on a face
b) shape detection to make changes only to anything resembling a series of shapes (circular, oval, partially closed bottom, partially closed top, etc.)
Just my 2 cents.

Not to worry - hearing from multiple people asking for the same feature can
highlight things that our users really want, and as such, helps us know what
should be prioritized.
