Only print error message in debug mode.

Only print error message in debug mode.

Currently, PictureTest runs a test of recording a bad bitmap to a
picture and then replaying the picture. We assert at the record
step in debug mode, so the test only runs in release, to ensure that
we can still play back a picture, even if it has a bad bitmap. Silence
the error message in release, so our test doesn't appear to error
(since it is actually working as desired).

Makes we wonder (again) if we can invent a cool way to capture
errors/warnings/failures through some sort of TLS callback/global/whatever, so
we can more formally test this sort of thing (and give more info to clients that
want it).
