std::vector<> has no data(), I think you want &*compressed.begin() like what was
here before.

Also, because WriteFile takes a const char* parameter as opposed to fwrite's
void*, the vector's type is significant.  We need a cast somewhere because
PNGEncoder::Encode expects an unsigned char*, so I've casted the one in
WriteFile to char*.
