Q3TriMesh_GetData

[Roger H. <rog...@mi...>]

I have had a problem with a corrupt 3DMF file which draws OK and seems  
fine until I do some complicated manipulations on it where my code  
gets everything which is not already a TriMesh into a TriMesh (or  
Triangle) and calls Q3TriMesh_GetData on all the objects. Part of what  
this gives me is an edge list which contains pairs of triangle  
indices. The problem came when I got a triangle index of 86 and there  
were only 11 triangles in the triangle list. This caused my program to  
crash.

I am now filtering the data I get back from Q3TriMesh_GetData and  
every index which is invalid gets set to 0xFFFFFFFF which means the  
edge has no triangle on that side.

So others don't have to spend two days debugging, would it be worth  
adding this extra processing to Q3TriMesh_GetData itself, or where we  
read the trimeshes in from the 3DMF?
