Color-to-alpha unnecessarily grayed out for grayscale images
With Image|Mode|Grayscale, the menu entry Layer|Transparency|Color-to-alpha... is grayed out. The feature does make sense for grayscale and one can even see that it works:
- open two grayscale images with alpha channel
- on first image ** set to Image|Mode|RGB ** apply Layer|Transparency|Color-to-alpha... ** set to Image|Mode|Grayscale
- on second image ** apply Filters|Repeat "Color to alpha"
=> the feature color-to-alpha can clearly be repeat-applied to a grayscale image without converting it to RGB, why not enable the menu item directly?
