Cursor: 8 -> 1 bit alpha downsampling improvement
Mouse cursors with 8 bit alpha were downsampled to 1-bit opacity maps by turning alpha values of 255 into 1 and everything else into 0. This means that mostly-opaque pixels ended up completely invisible. This patch changes the behaviour so that only pixels with less than 50% alpha (0-127) are treated as transparent when converted to 1-bit alpha. This greatly improves the subjective appearance of anti-aliased mouse cursors, such as those used by macOS, when using a front-end UI without support for alpha-blended cursors, such as some VNC clients.
