1920 x 1080 resolution - spheres are not on lines

[GoogleCodeExporter]

Fantastic program by the way - I found it early this morning but was 
distracted with work. Now I have it running and thought I'd create a video 
for the HDTV.

What steps will reproduce the problem?
1. I ran a data set at normal resolution then walked it up aiming for 
1920x1080
2. 1600x1200 seems fine, the further above 1600 introduces more and more 
visible drift
3. "drift" is when the center of clusters is no longer over top of the 
connecting lines.

command line - varying the 1600 factor.
gource.exe -1600x1200 --log-format custom --stop-at-end -a 3 -s 1 my-
project-gource.log

What is the expected output? What do you see instead?
expected to simply scale up the video to 1920x1080 w/o drift

What version of the product are you using? On what operating system?
v0.25 on Windows XP.latest

Please provide any additional information below.

Hi. What video card do you have and could you attach a screen shot?

Cheers

Andrew

It is an older ATI All In Wonder Radeon 9800 - with close to the latest AMD 
software 
drivers. This screen shot is at 1920x1080.

What happens if you do it full screen. ie add -f to the command line ?

I haven't experienced this because my monitor's native resolution is 1360x768, 
but that is some serious drift. It seems the farther away from the root the 
nodes get, the more they drift. The drift seems to range from about 100-400 
pixels.

Curious if anyone is still has this and would be willing to test a fix.

I think in some cases SDL is getting back a different resolution than the one 
requested, so Gource just needs to check the resolution it's actually using 
after the video mode is set, and no assume it's the one it asked for.

It turns out that when you set the video mode in SDL in Windowed mode, the 
OpenGL viewport doesn't necessarily match the dimensions you requested. Often 
it's out by a less than 10 pixels so it's hard to notice, but occasionally it's 
drastically out like the above.

Will be fixed in the next release (fixed on the gl2 branch right now).
