Skip out of canvas shapes for gridOutput() table

[limzykenneth]

Resolves #7130

Changes:

Add a check to see if the shape being iterated by gridOutput() is within the bounds of the canvas. If it is out of the canvas it won't be added to the table generated by gridOutput() (which only has entries for things within the canvas bounds).

@limzykenneth i still see a same or similar issue with 1.11.2 due to line exceeding y bound - just realized this is an older bugfix - but see here for minimal code to trigger the error: #7259 (comment)
