zihao.jiang 83d58ccfe8 GDI: Fix usage of gdi_get_brush_pointer.
Currently we get color from brush according to the offset in the paint region.
According to MSDN https://msdn.microsoft.com/en-us/library/dd183396(v=vs.85).aspx, it should get color according to dest position instead of offset in paint region.
