/** \file
* Regression test for bug #1754660 (reported by Alok Kulkarni) :
* Since QuesoGLC version 0.6.0, a call to glcRenderString draws only the
* first character of the given string when the call is executed as part of a
* user-defined OpenGL display list.
*
* For example, the pseudo-code:
*
* {
* ...
* glcRenderStyle (GLC_TRIANGLE);
* ...
* glNewList (id, GL_COMPILE);
* ...
* glcRenderString ("ABCDE");
* ...
* glEndList ();
* ...
* glCallList (id);
* ...
* }
*
* will render only the first character "A".
