  Tabs should be removed.

   Does it make more sense to #define KEY_ENUMERATE_SUB_KEYS if it's not available?

   Change to #if !PLATFORM(WINCE)

   Is this valid?

   Will this not affect the Win32 build?

   Can this be unconditional on WINCE?

   The difference here concerns me.

  Likewise.  Why are the coordinates behaving so differently?

   This looks like it will affect the Win32 case.  Should probably be checked in separately if it's valid there too.

   Same here.

KEY_ENUMERATE_SUB_KEYS is defined by OS header where RegOpenKeyExW is defined.

No, it won't affect win32 build. If GetProcAddress means GetProcAddressW, _T"" means L"". If GetProcAddress means GetProcAddressA, _T"" means "".

Because we support zoomed view. so frameRect().size() doesn't work for us

same reason as above.
