the expanded expander is misdrawn. It looks as if the triangle is not
exactly symmetric, causing some ugly aliasing. This is rumoured to be
related to floating point changes in gcc 3.4.1...
This really seems to be a compiler issue. Inserting any function call
- even g_free (NULL) - between create_affine() and the loop over the
points in gtk_default_draw_expander() fixes it.
