Thanks a lot - these are the things I was afraid of missing.

 I will change it and use 'overlay=x=0:y=0’ for clarity.

> I think overlay=0x0 is not doing what you expect. It does set the x option to hexadecimal 0, and it doesn't specify the y option. In your case that doesn't matter because the default values are 0. You could write 'overlay=x=0:y=0' or you could simplify it to just 'overlay' without any options.
