nit: Move this enum and the Kind one up above function declarations.

Add Mode & Kind prefixes to the enum values. This is another area where Blink
style differs from Chromium.

[Matthew Heaney (Chromium), 2013/04/18 23:15:42]

Done.

+  virtual void setMode(Mode mode) = 0;

[acolwell GONE FROM CHROMIUM, 2013/04/17 00:13:56]

nit: s/mode// . Blink doesn't specify parameter names when they don't provide
any extra info.

[Matthew Heaney (Chromium), 2013/04/18 23:15:42]

Done.

[acolwell GONE FROM CHROMIUM, 2013/04/17 00:13:56]

Yes this enum is necessary. Blink cannot have any dependencies on Chromium code.

[Matthew Heaney (Chromium), 2013/04/18 23:15:42]

Done.
