<p>m_advance is a vector that specifies where the basepoint should be moved to after the text is rendered. m_advance.i and m_advance.j are is always &gt;= 0. <br />
When glyphs are rendered right to left (Arabic and Hebrew being examples) or bottom to top, the rendering code must apply the correct sign. One reason is that Arabic and Hebrew text can be mixed with latin and Cyrillic text and text rendering is much more complicated than a signed advance can handle. Another is that the sign of y associated with "up" is sometimes positive and sometimes negative. <a class="el" href="../../dc/dec/class_o_n___text_box.html#a505af6299a249267f204a52dd0f3cf07">ON_TextBox::Translate</a> does not modify the vector m_advance. <a class="el" href="../../dc/dec/class_o_n___text_box.html#a993bccba8c25c101185f1d23051fee46">ON_TextBox::Union</a> ignored input advance values and returns a box with advance = (0,0). 0 &lt;= m_advance.i will be &lt;= m_max_basepoint.i. </p>
