some unexpected behaviors from minimize-restore-animations changes

[punker76]

i reverted some changes from the pr ##1514 minimize-restore-animations.

what happens:

• if a window starts with WindowState = "Maximized" the window is not completely maximized
• nasty window painting, if a user maximize or minimize the window (caused by ``WindowStyle = WindowStyle.SingleBorderWindow` )

/cc @Amrykid @flagbug @mrahhal @AdditionalPylons any ideas? if it's possible to fix, then it would be nice to enable/disable this, cause some people are not interessted by this animation (maybe)...

I just got back from a 3 week vacation so I'll look into this. Thanks for the finds.

@punker76 Hey, I'm currently looking into this again (After like... 7 months of not even looking at this problem). When you have time, could you try out https://github.com/AdditionalPylons/MahApps.Metro/tree/minimize-restore-animations
and let me know if the nasty painting bug is still there? I stepped through the frame by frame of a video capture, and can't seem to reproduce this issue. I assume that I'm either not doing the correct steps to get this bug, or my video capture missed the frames or something.

Thanks!
