Fix excessive dependency graph evaluation while painting strokes

Particularly noticeable when vertex painting with a subsurf modifier.

In some cases every sculpt or paint stroke step would evaluate the dependency
graph. This should only happen for redraws. Now more selectively choose if the
dependency graph should be evaluated to initialize the view context. Doing it
in the view context evaluation is somewhat hidden, now it's more explicit.
