I'd rather layer an EGL_MESA_cursor extension on top of the 
EGL_MESA_screen_surface extension than make it an integral part of it 
since there are devices that don't have/need cursors.

But cursors would be per-screen information, so you'd have queries like:

   eglQueryScreenMESA(dpy, scrn, EGL_MAX_CURSOR_WIDTH, &width);
   eglQueryScreenMESA(dpy, scrn, EGL_MAX_CURSOR_HEIGTH, &height);

And maybe set the position with:

   EGLint pos[2] = { x, y };
   eglScreenAttribsMESA(dpy, scrn, EGL_CURSOR_POSITION, pos);

Or, maybe a new function, such as:

   eglCursorPositionMESA(dpy, scrn, x, y);
