Our plugin does a little extra work in that it doesn't include an alpha
channel in the QImage if there isn't one in the WebP data when reading,
and vice versa when writing.

OTOH, our plugin's writing appears to be broken.  It also doesn't set
the "lossless" option ever, while Qt's plugin does.

Other than that, they're identical (unsurprising, since they both use
the reference libwebp).  So I would say that it's not worth keeping our
own once we depend on Qt 5.3.  The question is: do we want it for Qt 5.2
systems, or do we just say "if you want WebP, upgrade to Qt 5.3"?
