 Inside {{{bp_core_fetch_avatar()}}}, the {{{d}}} param is set like this:


 {{{
 if ( 'gravatar_default' !== $default_grav ) {
     $url_args['d'] = $default_grav;
 }
 }}}

 {{{$default_grav}}} will be either wavatar, mm etc. These are the
 "default" default images (generated by Grav). But Gravatar also allows
 {{{d}}} to be a URL:

 Ref: https://en.gravatar.com/site/implement/images/#default-image

 Is it possible to add a filter which lets us change the value of the
 {{{d}}} param before it's passed to Gravatar?

 I'm thinking {{{$params}}} would be useful to have in hooked functions
 because from that we could get the user or group ID etc.
