Comment 12 for bug 1010421

It seems odd gimp doesn't override the system and user's configuration of the rgba attribute to none, e.g. by providing a /etc/gimp/2.0/fonts.conf, e.g. https://gist.github.com/csaez/5d8286b134266e51c6cb76fd218d1d5d

If they think that a user might want to produce a PNG with rgba set for a particular sub-pixel layout then they could have a UI choice on the text-tool's options, just as they currently have anti-alias to override the system and user.
