wingdi.h定义的值如下：
#define PATCOPY (DWORD)0x00F00021 /* dest = pattern */
#define PATINVERT (DWORD)0x005A0049 /* dest = pattern XOR dest */
#define DSTINVERT (DWORD)0x00550009 /* dest = (NOT dest) */
#define BLACKNESS (DWORD)0x00000042 /* dest = BLACK */
#define WHITENESS (DWORD)0x00FF0062 /* dest = WHITE */
在MFC源文件trackrect.cpp中有(248-255行中)：
pDC->PatBlt(rect.right, rect.top, rectTrue.right-rect.right,
rect.Height(), 0x000F0001 /* Pn */);
最后一个参数什么意思
