[ft] Is it allowed to over-write FT_Outline pointers?

[Joe Krahn]

The routing FT_Outline_Decompose is helpful in converting the various 
outline segments to a set of straight-line points for use with drawing 
primitives. It can be convenient to store the result in-place, 
over-writing the point, contour, and tag array pointers.

Any chance that simply free-ing the 3 data pointers and over-writing 
them is OK? Or, is there a 'nice' way to do this? If not, am I likely to 
cause problems from alloc-ing my own FT_Outline structure?

Thanks,
