Simplified code:
+ re-use the bit mask as an inner loop counter.
+ turn alpha only rows into zero length with agreed lastPix.
+ keep lastPix around on the stack.
+ handle odd widths in a duplicate slow-path

When creating a delta, the copy command could copy from rows that are
bigger than the height of the tile. This would go unnoticed on light
mode because the js side that applied the delta would apply these out of
bounds rows with a white color, but it is noticable in dark mode. Made
it so the copy command stops copying from out of bounds.

zstd provides for much faster compression server-side, as well
as better decompression.
zstd allows us to de-compress a keyframe and several deltas in a
single call in JS, so it is necessar to add a terminator to the
delta stream so that we can detect when to flush the buffer we
are working on - so the next delta applies to the correct data.

Squashed from feature/deltas-expanded.
TileCache changes:
+ add montonic sequence (wid) numbers to TileData
+ account for sizes of TileData with multiple blobs
+ simplify saving and notifying of tiles
Sends updates (via appendChanges) based on the sequence the
right mix of keyframes and/or deltas required as a single
message, and parse and apply those on the JS side.
We continue to use PNG for slide previews and dialogs,
but remove PngCache - used by document tiles only.
Annotates delta: properly as a binary package for the websocket.
Distinguishes between deltas and keyframes we get from
the Kit based on an initial un-compressed prefix
character which we then discard.
kit can be forced to render a keyframe by oldWid=0
Track invalidity on tiles themselves - to keep the keyframe around.
We need to be able to track that a tile is invalid, and so subscribe
to the updated version as/when it is ready - but we also want to
store the keyframe underneath any deltas.
force rendering of a keyframe for an empty slot in the TileCache.
force tile sequence to be zero for combinedtiles - so the client can
always request standalone tiles with explicit combinedtiles, or tile
requests.
move Blob to Common.hpp
use zero size for un-changed tiles.
remove obsolete render-id, and color deltas in debug mode.
cleanup unit tests for non-png tile results.

Now the remaining tests that didn't have a name
get one and the logs are unified between old-
and new-style tests. Mostly.
This makes sure that all logs and assertions
properly log the test name and make test
failures easier to debug and fix.

Because the new-style tests are intrustive,
the exception that CppUnit throws on assertion
failures is caught and processed with the
application logic, which is far from ideal,
because it's very difficult to find the
cause of failure.
What we'd like is a way to control what happens
when an test assertion fails, such that we can
properly log/print the failure, and even break
in the debugger.
The new macros allow us to control the behavior
at compile-time and have added flexibility.
For now, they log an assertion failure before
invoking the CPPUNIT macro, and support a
compile-time directive to assert, which is
useful for breaking in the debugger.
