Function:s2qtxtyz
From S2PLOT
s2qtxtyz
Find the bounding box of text drawn with s2textyz.
Prototype
void s2qtxtyz(float *y1, float *y2, float *z1, float *z2, float x, float y, float z, char *text, float pad);
Description
Find the bounding box of text drawn with the s2textyz function. For convenience, pad can be given > 0.0 to obtain padding around the text of pad percent.
