[PATCH 0/4] MR5161: Draft: d3drm: Implement Update and related functions

[Jeffrey Smith (＠whydoubt)]

Regarding dirty rectangles:<br>
Documentation for `ForceUpdate` states that "The system might update any region that is larger than the specified rectangle, including possibly the entire window". While native seems to use a sort of dirty-rectangle approach, for this MR, I am simply dirtying the entire surface.  If someday someone did want to more-closely match the behavior of native, much can be learned from the rectangles passed to the update callbacks.
