Black tiles are returned when rendering fails.
This happened due to bccu#1610 where internally
core collected cell info on the first 1024 rows
only. Anything beyond that always failed.
This limitation is now removed using dynamic
array to collect the cell info.
Regardless, the test here needs only check that
the last tile (really, anything beyond the 1024th row)
doesn't return a black tile.
This single tile still takes over 10 seconds to render,
which is the other issue that Core suffers from when
collecting cell info on a huge tab.

A source file (.cpp) must include its own header first.
This insures that the header is self-contained and
doesn't depend on arbitrary (and accidental) includes
before it to compile.
Furthermore, system headers should go next, followed by
C then C++ headers, then libraries (Poco, etc) and, finally,
project headers come last.
This makes sure that headers and included in the same dependency
order to avoid side-effects. For example, Poco should never rely on
anything from our project in the same way that a C header should
never rely on anything in C++, Poco, or project headers.
Also, includes ought to be sorted where possible, to improve
readability and avoid accidental duplicates (of which there
were a few).
