### Graphics array formatting

I'm computing a number of plots (actually collections of 2d polygons) of roughly square aspect ratio, and would like to display them in a reasonable way:

- use two columns
- preserve order
- title each of them
- adjust the size to fill the width of my notebook, disregarding the height

First I displayed each graphics as it arrived, or combined bunches of them into `graphics_array`

in order to show them. But my sage notebook (the classical one, not the IPython flavor) failed to preserve order in that case. So I feel that I have to build one big `graphics_array`

.

But I've got trouble adjusting its width without specifying its height, and I don't know a suitable height up front. Most of the times if I specify one of the sizes too large, I end up with lots of empty space in one of the directions.

Furthermore, I didn't manage to title the individual graphics, since a `title`

attribute to the `polygon2d`

call remains without effect, while a `title`

attribute to the `show`

affects the whole plot and all the nested plots. Constructing an empty `Graphics(title="foo")`

doesn't seem to work.

This is on sage 6.10.beta4, so things might have improved since then. If so, I haven't yet found the appropriate locations in the online documentation indicating how this changed.
