[Mac, Win] New avatar bubble should be a fixed width.

[Mac, Win] New avatar bubble should be a fixed width.

This involves eliding ALL the things: the active profile 
name, the names of other profiles in the fast profile 
switcher, and the text of the big blue "add account for x" 
button.

Hi,

Here's some more work on the new avatar bubble that makes sure the bubble is
always a fixed size, and all of the text gets elided nicely. Please take a look!
Thanks.

You shouldn't need to elide the text yourself. You should set the bounds to the
right size and it'll elide appropriately. If that isn't happening, then I
suspect you're not configuring the layoutmanagers correctly.

Can these be defined in some shared location?
