Comment 7 for bug 936958

That bug does concider the fact that the desktop icon container shall be unchanged idependent of whether the kauncher is visible or not. That (design decision?) is stated in bug #684649.

The the left margin might be decreased or adjusted but not too low as this causes side effect especially with the launcher popping up as soon as one drags an icon on the screen.

Furthermore, the launcher's margin is registered i X and received from XGetWindowProperty. For a 32 pix wide launcher the left margin received is 49 pixels and for a hidden launcher it's 0 pixels. Tthis is why adding 66-15=51 to that left margin causes this issue.
