/* however compute these through the size's x_scale and y_scale, */
/* applied to the relevant face properties. */
/* The values of "ascender", "descender" and "height" are only the */
/* scaled versions of "face->ascender", "face->descender" and */
/* "face->height". */
/* */
/* Unfortunately, due to glyph hinting, these values might not be */
/* exact for certain fonts, they thus must be treated as unreliable */
/* with an error margin of at least one pixel !! */
/* */
/* Indeed, the only way to get the exact pixel ascender and descender */
/* is to render _all_ glyphs. As this would be a definite performance */
/* hit, it's up to client applications to perform such computations.. */
