[GTK] Media icons are loaded again every time style-set signal is emitted on every widget

[Carlos Garcia Campos]

We should change the colors when style-set is emitted, and load the icons only when the icon-theme changes.

Awesome patch. Just a couple issues outlined below.

> WebCore/platform/gtk/RenderThemeGtk.cpp:199
> +    g_signal_connect(gtk_icon_theme_get_default(), "changed", G_CALLBACK(gtkIconThemeChanged), const_cast<RenderThemeGtk*>(this));

Do you really need a const_cast here?

> WebCore/platform/gtk/RenderThemeGtk.cpp:794
> +    initMediaStyling(true);

This also reinitializes the media colors when the icon theme changes. Perhaps it would make sense to have two methods: initMediaColors and initMediaIcons.

> WebCore/platform/gtk/RenderThemeGtk.h:142
> +    virtual void initMediaColors(GtkStyle*);
>      virtual void initMediaStyling(bool force);

Why are these virtual? Does any subclass override them?

No idea, I copy-pasted from the "style-set" signal connection.

Updating the colors is cheap, so I thought it didn't hurt.

No idea, initMediaStyling was already virtual and I added initMediaColors based on it.
