Inaccurate line tracing

Although the two lines should be symmetrical...

But in reality, one line is one pixel offset, above the other.

Hi @buckle2000 ,

Thank you for raising this issue - and apologies for the very slow reply.

There was a small bug in the line function which meant that the last pixel was not being plotted. The offending line was this one. The equals was missing.

I've fixed this in version 1.2.10 and have added a new example (Example9) which demonstrates the correction. If you enable Serial debug messages using enableDebugging, you will see the coordinates of each pixel as it gets plotted.

Thanks again for spotting this.
Very best wishes,
Paul
