Well, it doesn't change actual behavior for SDL and cocoa.  It only adds
"-display {sdl,cocoa},show-cursor=on" as replacement for the global
"-show-cursor" option.  Guess I should reorder the patches (move 5/6
before the individual UI patches) and reword the commit messages.

If you think cocoa behavior isn't useful we can revert commit
13aefd303cf996c2d183e94082413885bf1d15bf instead, or drop the
cursor_hide check in hideCursor() + unhideCursor().  Your call.

It also adds gtk support (based on a patch by address@hidden).
