NewFromPNGData

Hello All:

It seems that Wx::Bitmap NewFromPNGData is not wrapped(didn't see any
reference to it in bitmap.xs).

wxWidgets defines it as:

public:
    // Create a new wxBitmap from the PNG data in the given buffer
    static wxBitmap NewFromPNGData(const void* data, size_t size);

What's involved in getting this wrapped?

Thanks,
James
