I'm recreating the video and the bitmap when I change camera dimensions. But it seems that once a video is snapshotted into a bitmap, the camera somehow remembers the resolution, and future snapshots of a new video object attached to that camera always end up at the same size. It doesn't make any sense and I can't even work around it because the first snapshot could have happened outside of this code. I did: - show some text behind the video, so that selecting a non-working camera gives a little feedback. - cleaned up NPE that happened if clearSnapshot() was called when it was already cleared. - Detach the camera from the old video before setting up a new one git-svn-id: svn+ssh://src.earth.threerings.net/nenya/trunk@467 ed5b42cb-e716-0410-a449-f6a68f950b19
