GdipBitmapLockBits assume bitmap is always top-down (positive stride), but it
may not always true, wine's gdiplus give a bottom-up one. I suggest checking
stride in DATA,
z=. |.^:(s<0) (h,w)$memr p,((s<0)*_4*w*h),(w*h),JINT
Also wine does not accept null pointer for rect in GdipBitmapLockBits, so you
may consider pass a valid rect structure to it by first calling
GdipGetImageWidth and GdipGetImageHeight.
I did not try but I think the current platimg will not run under win-x64.
