why not return ImeKeyboard::CapsLockIsEnabled(); ?

[FengYuan, 2014/11/04 07:11:19]

It's a placeholder, we should call the interface in Ozone, and return the value
from that.

Set/Get inconsistency would potentially break capslock indicator feature with
use_ozone=1.

[FengYuan, 2014/11/04 07:29:00]

Done.

[Shu Chen, 2014/11/04 06:17:08]

using SetCapsLockEnabled() to DisableNumLock() is the special trick for X11,
please leave this method empty.

[FengYuan, 2014/11/04 07:11:19]

Done.
