Bug 153076 – [GTK] Consistently use virtual and override specifiers in ScrollbarThemeGtk

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Michael Catanzaro]

Carlos made ScrollbarThemeGtk a final class, which I guess serves as an opt-in for new Clang warnings:

While we're at it... most of these functions have redundant virtual specifiers and override, while the rest have only override. I prefer to omit virtual when unneeded, and we don't currently have consistency within WebKit, but most of the other functions here use it, so let's do that.

Nah, the problem is that none of the functions were previously marked override.
