Fix Blitting in Metal backend. The Metal backend was clipping in integer space. If the src and dst are not the same size, say src is 3 wide and dst is 4 wide, and src starts at -1, then src will be clipped by one making the src 2 wide. It got 1/3 smaller so the dst get 1/3 smaller making it 2.666 pixels wide. The dst then needs to be expanded to pixels so 3 wide. But, that means the src also needs to be expanded 0.3333 * 3(originalSrcWidth) / 4(originalDstWidth) so its new left edge is -0.245 which is not an integer.
