It appears that the auto-indexing support in sqlite does not work on older mac osx hardware lacking firmware supporting 64 bit.

But if this reports EFI64 index creation works fine:

{{{
ioreg -l -p IODeviceTree | awk -F'"' '/firmware-abi/{print $4}'
}}}

Indexes are still created that look valid but the `_parent` table appears to have the wrong order leading to odd gaps in rendering when shapes are not matched right.
