Not the parent, but the problem is that applications that don't want to draw custom cursors are (or were except on gnome) still responsible for drawing the cursor. So instead of saying "i want a pointer cursor" when you hover over a link, you have to figure out what cursor theme the user is using, figure out what size you should use for the current screen resolution and scale, find the appropriate image for your desired shape, theme, and size, and render that to a surface. And hope you did all of that consistent with other apps the user uses.
