Thanks for you suggestions! Working with bytecode instructions must

Just for the fun of it, I installed the xgridfit. Learnt and wrote a
xgridfit version of the compute_stem_width() function. Porting the
pseudo code was fairly straight forward. Xgridfit has quite a rich set
of APIs. But the generated code is much longer than your hand craft
version, 400+ lines vs 150 lines. A lot of stack management codes.
Xgridfit lost in code size...
