Go ahead and fill in the font->info pointers so that bitmapUnloadScalable()
will free the bits that were allocated, even if some were not.
Error: Memory leak (CWE 401)
Memory leak of pointer <unknown> allocated with ComputeScaledProperties(...)
at line 1629 of /export/alanc/X.Org/git/lib/libXfont/src/bitmap/bitscale.c in function 'BitmapOpenScalable'.
pointer allocated at line 1616 with ComputeScaledProperties(...).
