Grayscale on a RGB image (whatever the image precision) gives different results.
This does not appear in branch gimp-2-8, since the 2 actions are computed the
same way (using GIMP_RGB_LUMINANCE).
In master, for Desaturate (luminosity) filter, GIMP_RGB_LUMINANCE is used on a
For Grayscale conversion, drawables' buffers formats are converted to
babl_format Y (or Y' according to the initial format).
As these 2 actions seem to have the same goal (obtain the relative luminance),
shouldn't we obtain the same result ?
