Maybe it would be better not to return 0.0 to indicate invalid axes, but 
HUGE_VAL for axisScaleMin and -HUGE_VAL for axisScaleMax. If i call 
axisScaleMin and get 0.0 in return, I still don't know if this is indeed the 
(valid) minimum, or of it flags some error.

I'm not sure if HUGE_VAL is defined in win32 environments, though. anybody 
out there with BCC or MSVC?
