This should be named m_pRecorder.

Can this be put in std::unique_ptr's so we don't have to worry about cleaning it
up?

The lifetime of the recorder is similar to a bitmap -- as PDFium is structured,
the bitmap isn't owned by the device or driver, but by the client caller. I put
a unique_ptr in pdfium_test.cc to mimic this structure. (done)
