I changed the maximum size that an image could be save at to 16384 by
16384 unconditionally so that we were not unnecessarily constraining
the user. There is no way to set this properly since the test occurs
in the viewer and the limit really comes from the engine, which may
have a different size if running client/server. The right thing to
do is remove the current test and replace it with a runtime check
in the engine. This resolves #1078.
