We should not consider this to be the permanent home of the
image_decode_color_profile.

I argue that this is appropriate *for now* because it reflects that the profile
is just once at initialization (unlike other IPCs like ViewMsg_Resize or
ViewMsg_ColorProfile, which can be sent multiple times).

When image decode color profile is dynamic in the renderer, ViewMsg_Resize or
ViewMsg_ColorProfile will be a better match for this functionality. But not now.

Of note is that because this is setting a static variable via initialization,
only the first call in this process will "count". While I wouldn't argue that to
be an ideal arrangement, I think it's the best we can do for the moment.
