Is the libmagick++ API stable?  We experimented with it a while ago,
and had problems over different versions.

The current implementation of imread calls jpgread and pngread when
appropriate, so loading png and jpegs should be (almost) as fast as
when using libmagick.  ImageMagick requires libpng and libjpeg, but I
guess it would be safer to depend on their implementation.

What I don't like about that solution is that we'll be needing a lot
of extra development headers, many of which we'll never use.  So we
should probably look into making use of more ImageMagick functionality
in other parts of the image toolbox as well.
