I tested fontmeta.ijs, it's much faster than scalex2 method but the text does
not look so nice.

when I try to use J504 metafile cmd, glplayext and glplayxywh are very difficult
to use, Could you also provide a fontmeta.ijs in J504?

Also I notice file size of the temp metafile is much bigger in J601, eg.
J504  12kb
J601  100kb

Is this expected?
