This fixes bug 1263.
The least significant 4 bits of wParam of a WM_SYSCOMMAND, SC_SIZE
message are supposed to be private, and are used internally in both
Windows and Wine to send an encoded hit test value.
An application that sends this message is supposed to only set wParam to
one of the SC_* values. Visual Foxpro however in addition sets the least
significant 4 bits, using the same encoding as used by Windows. In Wine,
this causes the wrong edge of a window to be moved.
This patch makes Wine use the same internal encoding for the bits as
Correctly encode wParam for WM_SYSCOMMAND,SC_SIZE messages.
