I think most users of Emacs on Windows do not build their own Emacs.
So, if we want GDI+ support to be tested so we can trust it, we would
need to "distribute" (as we do know, non-officially) two different binaries.
Which means that a user that knows nothing about the current image
libraries *or* GDI+ has to decide beforehand and without enough
information; or alternatively we would need to "push" the GDI+ build as
preferable, which would be weird for a new feature that can potentially
cause problems.
