Each Button has a KeyState, which may be shared with other buttons. The list of pressed and locked buttons is used as a list of keys, causing a search for the button in the current view.
This brings the appearance of the keyboard basically in line with what
was there before. The background and key borders still need to be fixed
and the text and icons should probably be drawn using the style context.
- use G_DECLARE_ and G_DEFINE_ macros
- move all data into ClassNamePrivate
- use _get_instance_private()
This should not introduce any functional changes or breakage.
Skipped two classes (EekKeyboard and EekboardContextService) for now in
order not to break the build.
These two classes are used in some very funky WIP code that tries to
circumvent encapsulation.
(Funky code is in eekboard/key-emitter.c and eekboard/eekboard-context-service.c)
