Yes. Use the Default Colormap. If you are using a Canvas to display
your images, you can set the Canvas Colormap with
screen_number = DefaultScreen( fl_get_display() );
fl_set_canvas_colormap( canvas,
DefaultColormap( fl_get_display(),
screen_number ) );
before the Canvas is shown.

Two solutions here. Either use one of the standard cursors with the
fl_set_cursor() function:
fl_set_cursor( FL_ObjWin( some_object ), XC_watch );
will display the X Windows watch cursor. Any good Xlib manual will
give you a list of the cursors and their symbols.
If you have a custom cursor, you can use fl_create_bitmap_cursor().
The manual discusses this in detail in Appendix B.

Forms may be placed arbitrarily using the FL_PLACE_GEOMETRY argument
to fl_show_form() along with the fl_set_form_position() or
fl_set_form_geometry() call. The manual also discusses this in
detail.
