Reviewed by Tim Horton.

The automatic resize feature controls whether or not the document
fitting scale is changed in response to the plugin's available width
changing. This is on by default but is disabled whenever any sort of
zooming occurs. We can keep track of this by adding some extra state to
PDFDocumentLayout that keeps track of whether the document fitting scale
should be adjusted during the layout of the document.

Zooming will update this state to disable the behavior. If the behavior
is disabled but the "Automatically Resize," context menu item is
selected, then the behavior will be enabled again, the zoom will get
reset to its initial value, and the document will need get laid out
again to compute the new document fitting scale.
