Support negative stride
Add support for negative stride to FrameBuffer Slice. Change data type of stride from size_t to ptrdiff_t. Add support for negative stride in `copyIntoFrameBuffer` and `copyFromFrameBuffer`. Add a new `testNegativeStride` test. Fixes: #614 Signed-off-by: 胡玮文 <huww98@outlook.com>
