Most of the parameters to this function map to fields

by the same name in UserProfile (avatar_source, realm_id,

email, etc.).

Then there are these:

medium - This means we want a medium-sized avatar. This can

affect the "s" parameter for gravatar avatars, or it

can give us something like foo-medium.png for

|
user-uploaded avatars.

|
|
|
client_gravatar - If the client can compute their own
|
|
gravatars, this will be set to True, and we'll avoid
|
|
computing them on the server (mostly to save bandwidth).
