lrint is faster here on -ftree-vectorize with GCC. This is likely simply
an artifact of GCC's rather terrible auto-vectorizer, since as per the
instruction set manuals cvtsd2si and cvttsd2si (or their vector equivalents)
have identical cycle timings.
Anyway, regardless of above, lrint is superior to round accuracy wise.
Safety guaranteed as long int has at least 32 bits.

lrint is at least as fast, and is more accurate.

In the code we keep using logo_x2-1 and logo_y2-1 rather than logo_x2
and logo_y2 themselves. Define them to be what we need instead, to avoid
the repeated subtractions.

The show option did not take clipping into account, so the borders on
the clipped side wouldn't show up. Fix it.

Relying on AVPixFmtDescriptor.nb_components is cleaner and faster than
checking data and linesize for every possible plane.

3835554bf8ed78539a3492c239f979c0ab03a15f made progress towards cleaning
up usage of the formats API, and in particular fixed possible NULL pointer
dereferences.
This commit addresses the issue of possible resource leaks when some intermediate
call fails.
Tested with valgrind --leak-check=full --show-leak-kinds=all, and manual simulation
of malloc/realloc failures.
Fixes: CID 1250334.
