Comment 17 for bug 722285

In response to comment #3, see patch enclosed.

Unfortunately, while with this patch one have plenty of room on the right side of the horizontal scroll bar, once the limit of 320*zoom_setting seconds of the project is reached, the canvas stops sliding.

It looks like the canvas has an absolute horizontal size. Is this what Andy meant when he said (#2) "The timeline object has a coordinate limit of around 32000 pixels, due to a limitation in libcairo"?

If this is the case, I am wondering whether we could get the left side of the project to get out of the canvas, in order to make room for the right side. Currently, because the left side of the project is hard-glued to the canvas, the right side (beyond the 320*zoom_setting seconds) is always outside of the canvas.

Any ideas, clues, hints or suggestions any one?
