   Support hiding slices to better understand what's on which layer,
   and to hide UI when not relevant.
   Requires using a HTTP server due to cross-scripting.

7. Bug 1624565 - Eagerly deallocate empty texture arrays in the texture … …

   …cache. r=gw
   
   We already have a cooldown from texture cache items being deallocated a certain amount of time and frames after their last use so we can deallocate texture arrays as soon as they are completely empty. We do this at the end of the frame to avoid deallocating and reallocating within the frame. It's better to reclaim texture memory this way than run into maybe_reclaim_shared_memory which will throw away everything and cause new allocations on the next frame.

8. Bug 1624565 - Avoid clearing the texture cache as often. r=gw …

   The current heuristic in TextureCache::maybe_reclaim_shared_memory pretty much clears the cache every 5 seconds. Clearing the cache is prtty drastic though, because it causes us to re-upload data and reallocate several textures on the next frame. We really only want to do it when the savings are big, which happens less often now that texture array layer count is capped at 16 and that textures are released as soon as they are empty.
   
   This makes us clear the cache less often by augmenting the threshold to 16 megabytes and only considering texture regions that would not be reallocated right away (since we grow some texture arrays more than one region at a time).

   …jrmuizel
   
   The texture array is currently grown layer by layer and we typically get to 3 or 4 layers over several frames by the time we are done loading a simple wikipedia page.
