The normal processing is
hinting scan-conversion
glyph data --------------> outline -------------------> bitmap
Since both FT_Outline_Render and FT_Render_Glyph work on outlines, no
hinting is involved if you call one of these functions.

The bitmap field in FT_GlyphSlotRec is for convenience. If you don't
render the glyph (this is, if FT_LOAD_RENDER is not used), the field
is not used.
Can you suggest an improvement to the documentation?
