We will take this opportynity to remove various QStyle specializations
from the public API in Qt5. This gives us much more freedom, for
example changing the inheritance hierarchy, pluginizing etc. without
worrying about BC.
=> Use QStyleFactory and/or QProxyStyle instead of creating an instance
or inheriting QFusionStyle directly.
