Witray + Dual Screen: witray is not kept on the same screen as the wmii bar

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Default WMII setup with witray on the right side
2. Comfigure dual screen with xrandr and primary output on the left screen == 
the screen with the wmii bar

I expect the witray to be on the right side on the wmii bar just beside the 
"status" but it appears on the right screen.

With my configuration, where the right screen is smaller and aligned to the 
top, the witray appears, not only the witray is on the right side, but also it 
is on the bottom of the "virtual screen" is an non visible part. So it is not 
even possible to see it.

Result can be found attached.

Wmii from mercurial build from source updated today:

I found where it comes from, but don't know how to cleanly solve the problem.

When the witray looks to find where to be put, it uses the whole virtual screen 
to set it's position. I think that it should use the real screens like the 
windows does.
The line that does the configuration is the line with "subpt(scr.rect.max, 
r.max);"
