Convert the character string into a series of glyph indices. 2. Place the pen to the cursor position. 3. Get or load the glyph image. *4.

Start over at step 3 for each of the remaining glyphs. 8. When all glyphs are done, set the text cursor to the new pen position. </quote> I believe my use of the term "pen" is the same as in the freetype documentation, no? And I thought that FT_Set_Transform is what is intended to implement step 4. Is that not correct? If not, then how is step 4 supposed to be implemented? And why is FT_Set_Transform unsuitable?
