Can you just include include wtf/PassRefPtr.h instead?

[timvolodine, 2013/04/10 19:06:12]

This is similar to how the WebDeviceOrientation is done. This is also how the
other classes in Platform/chromium/public are done i.e. WebData.h,
WebDragData.h. The #include "wtf/PassRefPtr.h" does not seem to work because it
is not in the search path.
