I'm almost certain the canvas limits of +/- 8,388,608 only apply for
later versions of goocanvas. For a long time, all the distros have
shipped version 0.15 of goocanvas - it is now at version 2.0.1. The
important part from that page is this:

<< Prior to Cairo 1.6 16 bits were used for the integer part and 16 bits
for the        fractional part, meaning values were limited to +/-
32,768 >>

On my system (Linux Mint 11), Cairo is version 1.10.

However, in the last few weeks goocanvas 2.01 has finally been packaged
in Ubuntu, although strangely not in Debian. So hopefully soon we can
make some progress on this issue. It might not be totally
straightforward though, as we will somehow have to deal with all the
potential users who won't be on the latest distros and so won't have
goocanvas2.

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
