Re: [Fenfire-dev] (Alph) PEG imagescrollblock--humppake

[Hermanni Hyytiälä]

Hi,

Um...it would be nice to know what was *the initial reason* why this PEG
has been proposed. That is, PEG's author should make this clear in intro
so, for example, a reader who has not followed discussion intensively 
in the mailing list could understand the reasoning for the creation of a
PEG.
