/* How the resize system works:

    First, you need to add a WWT_RESIZEBOX to the widgets, and you need

     to add the flag WDF_RESIZABLE to the window. Now the window is ready

     to resize itself.

    As you may have noticed, all widgets have a RESIZE_XXX in their line.

     This lines controls how the widgets behave on resize. RESIZE_NONE means

     it doesn't do anything. Any other option let's one of the borders

     move with the changed width/height. So if a widget has

     RESIZE_RIGHT, and the window is made 5 pixels wider by the user,

     the right of the window will also be made 5 pixels wider.

    Now, what if you want to clamp a widget to the bottom? Give it the flag

     RESIZE_TB. This is RESIZE_TOP + RESIZE_BOTTOM. Now if the window gets

     5 pixels bigger, both the top and bottom gets 5 bigger, so the whole

     widgets moves downwards without resizing, and appears to be clamped

     to the bottom. Nice aint it?

   You should know one more thing about this system. Most windows can't

    handle an increase of 1 pixel. So there is a step function, which

    let the windowsize only be changed by X pixels. You configure this
