- 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)
A new class EekClutterDrawingContext maintains the context used to draw actors. Single EekClutterDrawingContext instance is shared by EekClutterKeyboard, EekClutterSection, EekClutterKey, and EekClutterKeyActor.
