[PATCH 3/5] winemac.drv: Stop cursor clipping when a window is resized by dragging.

[Tim Clem]

Testing on Windows confirms this behavior.

Signed-off-by: Tim Clem <tclem at codeweavers.com>

For undecorated windows, this already happens via
WINPOS_SysCommandSizeMove, which explicitly calls ClipCursor(NULL). For
decorated windows, that WM_SYSCOMMAND isn't issued for live resizes, so
this callback to the application contoller is necessary.

Note that ef46771 locked windows when the cursor is clipped by default.
The Mac driver registry key CursorClippingLocksWindows must be set to N
to enable this behavior.
