- Do not set emit the enabledChanged of the text-input-v2 when it
requests us to show input panel, it is already enabled when you get
this request
- If we get the request to show input panel, reset the inputContext,
there's two reason we can get this event: 1) when keyboard focus is
activated or 2) when keyboard focus is changed to text field in same
surface. In both cases, information in input method context is not
valid anymore and should be reset.
- Also instead of ignoring the update_state events from client, adopt
input method accordingly.
VirtualKeyboard class does not implement the relevant VirtualKeyboard
protocol but rather implements the InputMethod protcol and can in theory
be used by other input method like e.g. ibus.
Make class name consistent with what it does to avoid confusion in
future.
For now only rename of main class is done and dbus service is kept as-is
to provide retro-compatibility, when input method protocol is
implemented fully, we can think of what to do wrt the dbus interface
later when we fully implement zwp_input_method_unstable_v1 protocol.
