[Devel] Most efficient flags to use with FT_Load_Char to get ONLY metrics ?

[Rich Stephens]

If I am going through the characters in a certain charmap and I really only want to
glean the information in the face->glyph->metrics structure and not the bitmap or
vector image for rendering, could someone recommend the most time-efficient
flags to use with FT_Load_Char?  I'd still like the values to be as they would
when I use FT_LOAD_DEFAULT, but if there's any I can use that might speed up the
process, I'd like to hear about them.

For instance, it appears that FT_LOAD_NO_BITMAP might be of help.  Am I right?  Are
there any more?

This is the impression I got while discussing this topic with various
people.

The current version of 5005.BDF (2.2, dated 1993) doesn't include
support for graymap fonts.

Interesting.  I've never used those tools -- Mark, can you please give
more information?

Anyway, the extension is straightforward IMHO.
