Rich Geldreich 81464a6d6b Changing the ETC1S->BC4 and ETC1S->ETC2 EAC transcoders so they convert from the source red channel, not source green. Source red makes more sense when transcoding to BC4/BC5, especially when the source texture only has color slices. BC4 is red, and BC5 is red/green. This change makes no difference if the source texture slices are grayscale.
