Historically, this function has been described as returning a pixel-width, but was implemented to return the width in model-space units, rounded to integers. GLUT never resolved this, and freeglut duplicated the confusion. OpenGLUT has decided to stay in model-space and to return the unrounded floating point value. An unreleased GLUT 3.8 was supposed to include glutStrokeWidthf() and glutStrokeLengthf() (note the *f suffixes), but that is not in wide use.
