The toc is inexact and not using it can thus make sense.
Using it is faster though, thus the opposite can similarly makes sense

We need at least one pixel around the logo to use as known points to
interpolate from. So properly declare the band/t attribute has having
a minimum value of 1.

Options "show" and "band" are unrelated and should thus be
independent. However, setting "show" to 1 currently resets "band" to
its default value of 4. While this is documented, this still
surprising and confusing IMHO.

Change this behavior and make "show" and "band" independent from each
other. Update the documentation accordingly.

The left and right samples are the same for the whole line, so store
their values and don't recompute them for every iteration of "y".

This simple optimization results in a speed improvement between 15%
and 20% in my tests (depending on the logo geometry.)

Result is obviously the same.

The top left hand corner pixel coordinates are already stored in
logo_x1 and logo_y1 so don't recompute each of them 6 times for every
iteration.

This is a simple code optimization, result is obviously the same. The
performance gain is small (about 2% in my tests) but still good to
have, and the new code is clearer.
