Subject: The Java console keeps showing up error reports due to being asked
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/puzzles/commitdiff_plain/cb22d3a69ec93769fbf22fa1535892c92e36f99d

The Java console keeps showing up error reports due to being asked
to resize the puzzle to zero size. Ignore all such requests, in the
assumption that a more sensible resize will be along soon enough
(which does seem to happen, though I haven't debugged the NestedVM
front end hard enough to figure out why the bogus resizes happen in
the first place).
