Dragging tabs in/out

[chinhster]

2 issues with a miniwindow tear off.

If you drag a tab out of the main window on (or to) a secondary display where the top of the secondary display is lower than the top of the main display, the new window that's created has the titlebar above the top of the secondary display. You can't drag the new window because you can't get to the titlebar.

If you drag a tab item within its parent tabview to reorder it, the miniwindow appears under the mouse pointer as you move it around as expected. However, if you try to drag the last tab item from one window to another window, the tab item's parent window is closed and no miniwindow appears under the mouse. Drag and dropping does work, you just don't see what you're dragging and dropping.

I haven't noticed any obvious issues with alpha window tear off which is what I'll be using anyway.
