Static analyzer warning about memory allocation in cpPolyline

[richardgroves]

Line 247 of cpPolyline -

Chipmunk2D/src/cpPolyline.c

Line 247 in edf83e5

set->lines = (cpPolyline**) cpcalloc(set->capacity, sizeof(cpPolyline));

is allocating an array of size cpPolyline objects and assigning it to a cpPolyline** - should the sizeof be sizeof(cpPolyline*) ?

XCode analyzer complains:

Also has the same problem with

Chipmunk2D/src/cpPolyline.c

Line 316 in edf83e5

set->lines = (cpPolyline**) cprealloc(set->lines, set->capacity*sizeof(cpPolyline));

I reviewed these lines and their context: I agree with the assessment. It allocates more memory that necessary.
