Fix issue with thick lines
Fix issue with thick lines

On systems that did not support lines wider than 1.0 there
was still a case where glLineWidth was getting called. Mainly
when drawing triangles or strips but not in WIREFRAME. This fix
makes it so that it is only called when they are in wireframe.
