Should we allow setting pageScale?

[bokand]

My initial draft has scrollLeft and scrollTop as writable but pageScale as read-only. On reflection, a writable scroll offset seems pointless without a writable pageScale. We should either make them all read-only or all writable.

I am not sure if writable scrollTop/scrollLeft is entirely pointless since a site may want to adjust things based on a changed page scale (by the user).

In any case, I agree that making pageScale writable can be useful.

+1 for scrollTop, scrollLeft, and pageScale all being writable.
