What is the suggested way to write messages on top of performer image.
Here is what I've found so far:

/* Draw a message justified wrt to x,y in font of size 'size'.
 * 'just' may be CENTER, LEFT, RIGHT. x, y should range from 0 to 1
 * and 'size' should be SMALL, MED, or BIG.
 * The colors of the message are fixed: purple text with black shadow.
 * This is ageneral and expensive routine and is meant to be used for
 * fairly static messages that only need updating upon a REDRAW event.
 * For messages that need to be
 * updated frequently, a more streamlined routine should be used.
 */
void
pfuDrawMessage(pfChannel *chan, const char *msg,
                int rel, int just, float x, float y, int size, int cimode)

When I use it (messages change each frame) I get considerable flicking.
How can I avoid it or is there any other convenient way to write messages?

Many thanks in advance!
