Subject: [PATCH] Adding a new option to disable the cursor pushback for active
 screen edges. I haven't added it to the UI as the screen edges kcm is already
 a little bit cluttered with complicated options. So if you want to disable
 the pushback add option "ElectricBorderPushbackPixels" to section [Windows].
