As suggested in #8939. This results in some minor changes for emscripten and x11. Both previously mapped SIZEALL to "move", but "move" is not guaranteed to be a four-pointed arrow: according to the CSS spec, it's actually intended to be a drag-and-drop cursor, analogous to "alias" and "copy". Map it to "all-scroll" instead, as in Wayland: while this is *also* not semantically guaranteed to be a four-pointed arrow, it is at least *suggested* to make it a four-pointed arrow. Also, emscripten was previously using two-pointed arrows for resizing (BOTTOMLEFT mapped to "nesw-resize", and so on). This commit changes it to use the more specific "sw-resize" and so on, which might be single-directional. Signed-off-by: Simon McVittie <smcv@collabora.com>
