Windows: Fix maximizing frameless windows on secondary screens.

They would either disappear or be positioned at bogus coordinates.

The MINMAXINFO structure works with coords from the primary screen
then uses an "interesting" algorithm to adjust to secondary screen:

Say you have a primary screen with width=1000 and secondary screen
with width=2000, here's what you get when you set ptMaxSize to:

ptMaxSize.x   | Size window gets in second screen
--------------------------------------------------
    500       |                500
    1000      |               2000
    1001      |               2001
    1100      |               2100

So basically you can't get any value between 1000 and 1999

How many people use the taskbar on a second display and maximimize
a frameless window anyway ?
