Some minor style nits below.

> Source/WebCore/platform/chromium/ScrollbarThemeChromiumAndroid.cpp:66
> +    float proportion = (float)scrollbar->currentPos() / scrollbar->totalSize();

WebKit preferes C++ style casts, so static_cast<float>(...)

> Source/WebCore/platform/chromium/ScrollbarThemeChromiumAndroid.cpp:103
> +namespace {

WebKit tends to use static functions rather than anonymous namespaces.

> Source/WebCore/platform/chromium/ScrollbarThemeChromiumAndroid.h:53
> +    static const int s_scrollbarWidth = 8;
> +    static const int s_scrollbarMargin = 5;

WebKit doesn't use the s_ prefix for static variables.  We just use bare names like scrollbarWidth (and we tend to put them in the implementation file rather than the header if they're not used outside the implementation).
