ScaledFont.glyphExtents

Gets the extents for an array of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by cairo_show_glyphs() if the cairo graphics state were set to the same font_face, font_matrix, ctm, and font_options as scaled_font). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by cairo_show_glyphs(). Note that whitespace glyphs do not contribute to the size of the rectangle (extents.width and extents.height).
