Snapshot improvements.

Browse Source 
* Warn when it was not possible to make a snapshot because the difference
between the aspect of the required target size and the required target
aspect itself is too large.
* Reset Feed and Postcard Aspect to Default when making a new snapshot.
* Fixed a rounding error that caused one-pixel size error.
