- Move palette() from deprecated QtWidgets/QGuiPlatformPlugin
to QtGui/QPlatformTheme, Make it return a const * since
QPalette does not have isNull().
- Initialize QGuiApplication::palette() and
QApplication::systemPalette() from it.
- Do not initialize QPalette from QGuiApplication::palette()
unless app_pal is non-null (default to Qt::black if it is 0).
This avoids initialization order crashes/recursions in the
QPA plugin. Streamline initialization function.
- Remove styleName(), systemIconThemeName() and iconSearchPaths()
from QGuiPlatformPlugin and re-add them as
QPlatformTheme::themeHint().
- Remove styleHint() from QGuiPlatformPlugin, add it to
QPlatformTheme::themeHint().
- Add UNIX themes with factory function (Generic,
KDE, Gnome), taking it from Qt 4.8 code (stripping the
KDE 3 code).
- Implement Windows palettes.
