class="small-caps">G</small><small

often.

     <ul class="itemize1">
     <li class="itemize">do not keep track of the bounding boxes,

     <li class="itemize">do not allow you to arc corners,

     <li class="itemize">do not apply coordinate transformations.</li></ul>
<!--l. 31--><p class="indent">   However, they do use the soft-path subsystem (see Section&nbsp;<a 
href="pgfmanualse34.html#x35-32300034">34<!--tex4ht:ref: section-soft-paths --></a> for details), which allows you to mix quick and
normal path commands arbitrarily.

     <!--l. 145--><p class="noindent">This command works similarly to the <span class="obeylines-h"><span class="verb"><span

     <span 
class="cmti-10">number</span><span

     matrix (is it &#8220;synced&#8221; with this matrix, hence the name).
     <!--l. 151--><p class="noindent">Thus, this command basically has the same effect as if you first called <span class="obeylines-h"><span class="verb"><span 
class="cmtt-10">\pgflowlevelsynccm</span></span></span> followed by
     <span class="obeylines-h"><span class="verb"><span 
class="cmtt-10">\pgfqbox</span></span></span>. However, this command will use <span class="obeylines-h"><span class="verb"><span 
class="cmtt-10">\hskip</span></span></span> and <span class="obeylines-h"><span class="verb"><span 
class="cmtt-10">\raise</span></span></span> commands for the &#8220;translational part&#8221;
     of the coordinate transformation matrix, instead of adding the translational part to the current canvas
     transformation matrix directly. Both methods have the same effect (box <span 
class="cmsy-10">&lt;</span><span 
class="cmti-10">box number</span><span 
class="cmsy-10">&gt; </span>is translated
     where it should), but the method used by <span class="obeylines-h"><span class="verb"><span 
class="cmtt-10">\pgfqboxsynced</span></span></span> ensures that hyperlinks are placed correctly.
     Note that scaling and rotation will not (cannot, even) apply to hyperlinks. </dd></dl>
