sw_engine SwShape: Prevent null access

Browse source 
strokeOutline returned strokeExportOutline() is the address of mpool->strokeOutline[idx].
Assuming this value is null, mpoolRetStrokeOutline on line 617 will access mpool->strokeOutline[idx].
Logically, the logic of the mpool* functions does not occur in this case.
