[2.0.61] --dump-icon-sprites shifts everything southeast by one pixel

[Quezler]

steps to reproduce:
- run factorio with said commandline option
- head into script-output and navigate to an icon that touches all the sides, like the deconstruction planner
- notice there is a 1px margin at the left and top, and the bottom and right have 1px cut off, the output is still 64x64, it just got shifted out of bounds.

Thanks for the report. This is now fixed for the next release.
