[GTK] Move scrollbar rendering out of gtk2drawing.c

[Martin Robinson]

This bug tracks moving scrollbar rendering out of gtk2drawing.c. This is the final piece of the Mozilla theme drawing code that we use, so we can remove these files completely once this bug is resolved.

I will change the underscores here to dashes before landing.

s/draw not/not/, right?

Xan does not approve of using g* types when they're just typedefs of the standard C ones.

> Source/WebCore/platform/gtk/WidgetRenderingContext.cpp:155
> +void WidgetRenderingContext::gtkPaintBox(const IntRect& rect, GtkWidget* widget, GtkStateType stateType, GtkShadowType shadowType, const gchar* detail, bool adjustAllocation)

Would it hurt to remove the bool and always perform the allocation? I mean, except for the (negligible?) extra work? It might make this more future-proof, and we can toss this additional argument.
