Here's amended patch.

2 all: feel free to test/use it, but be aware that it will leak
memory  until getWMHints is fixed in X11.

[Partial fix for #40
Spencer Janssen <spencerjanssen at gmail.com>**20081007212053
  - clicking on the root will change focus to that screen
  - moving the mouse from a window on a screen to an empty screen changes focus
    to that screen
 The only remaining issue is that moving the mouse between two empty screens
 does not change focus.  In order to solve this, we'd have to select motion events
 on the root window, which is potentially expensive.

[Remember if focus changes were caused by mouse actions or by key commands
Klaus Weidner <kweidner at pobox.com>**20080502175603
 If the user used the mouse to change window focus (moving into or clicking on a
 window), this should be handled differently than focus changes due to keyboard
 commands. Specifically, it's inappropriate to discard window enter/leave events
 while the mouse is moving. This fixes the bug where a fast mouse motion across
 multiple windows resulted in the wrong window keeping focus.
 It's also helpful information for contrib modules such as UpdatePointer - it's
 supposed to move the mouse pointer only in response to keyboard actions, not if
 the user was moving the mouse.
