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?

Title:
  timeline only shows 320 times the zoom slider setting

Status in libcairo  -  cairo vector graphics library:
  Confirmed
Status in OpenShot Video Editor:
  Confirmed

Bug description:
  The timeline only shows the first (320*zoom seeting) seconds of a project.
  So if the zoom slider setting is set to 1 s, the timeline stops at 5'20'' (=320'')
  if it set to 2 s, it stops at 10'40'' (=640''), 4 s it stops at 21'20'' (=1280''), etc.

  How to reproduce:
  -launch OpenShot and create a new project of 60 min
  -with the default 8 s zoom setting you can only move the timeline up to 42'40'' (=2560 = 320*8)
  -try zooming in and see the timeline shorten as you zoom more

  1. Ubuntu 10.10 x64
  2. PPA installation
  3. OpenShot 1.3.0
