Only increment seqId when a new draw is actualy needed

At times WM may queue up a window to be resized just to
report changes that don't actually require a redraw (eg
insets). In these cases, skip incrementing the seqId.

Also, fix a couple tracepoints and other bugs like
VRI not updating lastSeqId when relayout was skipped
for a particular configuration
