delay, collect and compress LOK invalidations for Writer views

Due the to way views are updated on any document change, invalidations
are at least O(n^2), and since LOK may use a number of views and
for each view the entire document is considered to be the view area,
this can lead to a huge number of invalidations that are mostly
the same repeated rectangles.
