1. Bug 1605283 - Improve support for invalidation debugging and testing … …

   …r=gw
   
   Optionally serialize N frames into a circular memory buffer, and save
   them as part of wr-capture into tilecache/.
   
   The new tile_view utility reads the folder and converts the frames to
   svg for easier visualization, with a few extra features:
   - color code each primitive based on which slice it is on;
   - highlight new or moving primitives in red (brute force diff);
   - print all invalidated tiles at the top and the invalidation reason;
   - overlay the tile quadtree to visualize splitting & merging;
   - HTML and JS wrappers for animation playback, timeline scrubbing;
   
   Positioning of the tiles on the screen is a bit broken still; especially
   during scrolling and "special" pages (like about:config).
   
   Interning info is not used yet.
