[PATCH 04/12] Cygwin/X: When the style changes, adjust the window size so the client area remains the same.

[Jon TURNEY]

When the style changes, adjust the window size so the client area remains the same.
Otherwise the window size may change when sizing is reflected from
Windows to X, and some windows are drawn expecting them to be exactly the requested size
(e.g. gmplayer control window)
