why is this a dictionary rather than a typed object?

[paulmeyer, 2015/01/20 19:12:09]

Because |create_params| needs to be a DictionaryValue to get passed into
CreateGuest() at the other end of the IPC in
OnExtensionCreateMimeHandlerViewGuest. It is also consistent with
|attach_params| in ExtensionHostMsg_AttachGuest right above.

Why did OnExtensionCreateMimeHandlerViewGuest change to take a DictionaryValue?

[paulmeyer, 2015/01/21 15:25:55]

Okay, I replaced the DictionaryValue with an IPC struct.
