Query and set the GLE cylinder and cone roundness. When GLE draws a cylinder or a cone, it approximates the circular
cross-section with a polygon (of 20 sides by default). These subroutines can be used to change the default number of
sides in this cross-section. A smaller number of sides can typically be drawn much faster, at the loss of some visual
accuracy. Increasing the number of sides to more than 20 will typically have no noticable visual effect.
</p></div><div class="refsect1" lang="en"><a name="gleSetNumSides.3GLE-bugs"/><h2>Bugs</h2><p>
Multiple threads using GLE share a single global number of sides (although this should be easily fixable because GLE
does use a centralized graphics context).
