In this case I'm keeping it as-is since ImageButton only has a version of
SetImage() that accepts a const ImageSkia* parameter (calls to
ImageButton::SetImage() elsewhere in the codebase seem to follow the same
pattern).

If you'd like, in a follow up CL I could try introducing an overloaded version
of SetImage() to ImageButton, or I could make |image_md| into a member variable
of VirtualKeyboardTray. Just let me know if you think either of those would be
worthwhile.

That's OK, it's fine as it is. There seems to be a lot of variation in the code
base between const ImageSkia* and const ImageSkia&, but that's an issue for
another day.
