Comment:

 Our alfont code is almost identical to the code from upstream AGS and I
 could not detect a difference that would explain the crash.

 It does seem to have an inconsistency between
 `alfont_get_font_real_height()` and the `max_bmp_y` computed in
 `alfont_textout_ex()`, causing the allocated surface to be smaller than
 expected for the draw by a few pixels. There are a number of hack on the
 computation of the real height, so possible one of those is the culprit.
 But I don't want to start changing those hacks, so instead I have added a
 sanity check in `putpixel()` to make sure we do not attempt to write
 outside of the surface.
