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)

If it doesn't work, you're not hitting it with a big enough hammer
