[Feature Request] Basic Floating

[Andonome]

Right now, an image at the end of a grid column enters the next column. Would it be possible to acheive basic floating with a #float command which moves the target image (or anything else) to the top of the next grid, but continue placing the text in the first column?

It would also be good to have a command which lays the object outside of any current grids, so that a wide image could 'float' to the top or bottom of the next page.
