Extend Format to Bounding box, restore original Format.

This more a personal reminder than anything else but I thought I might as well store it here instead of my notes.

This is intended to ease the use of notes and gizmos that handle out of format pixels poorly. It extends the format to the whole boundingbox and then restores it to its original size, allowing you to do whatever needs doing in the middle.
