Reserved area at the right border - without a panel being there and with all margins set to zero

Description

When opening new applications (e.g. tunar, leafpad, ...), there is always a reserved area at the right side of the screen. In a dual-screen configuration, there is a reserved area on the right side of both screens. This would be OK if there was a panel on the right side. But I don't have any. Only at the top and bottom.

Steps to reproduce:

• switch to an empty virtual desktop.
• open a leafpad from the XFCE menu. verify it is at the left side.
• open another leafpad from the XFCE menu.

Expected behaviour: Should open at the right side, touching the border.

Real behaviour: Opens at the right side, with a small distance to the border.

Applications that manage their size and position themselves (e.g. geany) are not affected.

While it is "only a bit annoying" for xfce applications, some 3rd party applications that try hard to manage their position and size appear to be "forced" by Xfwm4 to keep a distance to the border, screwing up their layout. E.g. Intellij IDEA and PyCharm.

But as the reserved area applies to XFCE applications too, I would say it is a Xfwm4 issue, not an application issue.

And because screens are always too small, I do not want to waste a single pixel ... :-)
