This is especially noticeable when using the default center with full
width and height as some borders are masked by 1 pixel.
The relative coordinates are now calculated respect the last ones
instead of the dimensions for centering, and the limits
are inclusive to mask more accurately.
Adds full frame implementation to this node operation.
No functional changes.
