* Rejig handling of scrolling views. Ensures, among other things, that playing when there is a scroll mode view present (e.g. a spectrum) does not drag any page mode views into scroll mode with it.

Chris@55 45 Some notes about the SV XML format. We're very lazy with our XML:
Chris@55 46 there's no schema or DTD, and we depend heavily on elements being
Chris@55 47 in a particular order.

Chris@55 57 <!-- id numbers are unique within the data type (i.e. no two
Chris@55 58 models can have the same id, but a model can have the same
Chris@55 59 id as a layer, etc). SV generates its id numbers just for
Chris@55 60 the purpose of cross-referencing within the current file;
Chris@55 61 they don't necessarily have any meaning once the file has
Chris@55 62 been loaded. -->

Chris@55 81 model attributes give the source model id and target model
Chris@55 82 id respectively. A model can have both dataset and
Chris@55 83 derivation elements; if it does, dataset must appear first.
Chris@55 84 If the model's data are not stored, but instead the model
Chris@55 85 is to be regenerated completely from the transform when
Chris@55 86 the session is reloaded, then the model should have _only_
