Log message:
* More portability fixes as suggested by Petr
* The libggi API recently changed the semantics of ggi_mode.size to mean
mm instead of pixels- used ggi_mode.visible instead.
* Implemented on_control style functions (not fully correct yet).
* Enabled the standard debugger (not the on-screen one) again.
* Implemented three gfx_* debug functions

The libggi API change problem caused an FPE in what appeared to be a
corrupted stack. However, this was caused by a division by zero in the
initialization part of a function that had just been linked dynamically,
which, in turn, was caused by ggi_mode.size.(x,y)/(320,200) returning
zero. Figuring this one out was... interesting.
