Rendering: Use AdjustWindowRect to ensure pixel perfect client size

Continuing in the vein of commit 5f8b3c0c this commit eliminates more
(less often seen) calls to GetSystemMetrics to yield proper window
sizing by calling AdjustWindowRect. This takes window borders into
account properly across more versions of Windows.

Specifically, this change should fix the failing
vtkRenderingCoreCxx-TestTilingCxx test from the mug.neocisinc
dashboard client.

After this change, there are NO calls to GetSystemMetrics in this file.

Rendering: Retrieve the full screen size in GetScreenSize

On Windows, setting a render window to go "full screen" would leave the
Windows task bar showing, and have the render window only taking up
*most* of the screen.

Change vtkWin32OpenGLRenderWindow's GetScreenSize method to retrieve
the full size of the screen on the primary monitor and allow Windows
apps to have truly full screen vtkRenderWindows.
