If that's the case, (I could use the below function to theoretically display a character by character), it is this an efficient use of this function to display character by character message keeping track of the cursor this way? Or effecient is not an issue here?
Is there a mechanism for doing this any other way?
Thanks.

I think you are looking for this API call:
/**
* GrGetGCTextSize:
* @gc: the graphics context
* @str: pointer to a text string
* @count: the length of the string
* @flags: text rendering flags (GR_TF*)
* @retwidth: pointer to the variable the width will be returned in
* @retheight: pointer to the variable the height will be returned in
* @retbase: pointer to the variable the baseline height will be
returned in
*
* Calculates the dimensions of the specified text string using the
current font
* and flags in the specified graphics context. The count argument
can be -1
* if the string is null terminated.
*/
void
GrGetGCTextSize(GR_GC_ID gc, void *str, int count, int flags,
GR_SIZE *retwidth, GR_SIZE *retheight, GR_SIZE *retbase)
