Function drawLine() fails to heed setSerieWeight() if not anti-aliased nor setSerieTicks() used

[Lerrissirrel]

I'm placing this here more for anyone who comes after me than to expect a solution.

It appears that, for whatever reason, drawLine() ignores setSerieWeight() if neither anti-aliasing nor a dashed (ticks) line are requested. My best guess is that the author thought that thick lines looked bad without these settings. Or it could have just been an oversight.

There's an old question about this on the "official" (dead?) pChart forum: http://wiki.pchart.net/forum/viewtopic.php?f=5&t=2316&hilit=setserieweight

I found no harm when commenting out this clause in drawLine() to let it fall through to the code that handles the weight.

if ( $this->Antialias == FALSE && $Ticks == NULL )
      {
       if ( $this->Shadow && $this->ShadowX != 0 && $this->ShadowY != 0 )
        {
         $ShadowColor = $this->allocateColor($this->Picture,$this->ShadowR,$this->ShadowG,$this->ShadowB,$this->Shadowa);
         imageline($this->Picture,$X1+$this->ShadowX,$Y1+$this->ShadowY,$X2+$this->ShadowX,$Y2+$this->ShadowY,$ShadowColor);
        }

       $Color = $this->allocateColor($this->Picture,$R,$G,$B,$Alpha);
       imageline($this->Picture,$X1,$Y1,$X2,$Y2,$Color);
       return(0);
      }

Hey, how about you create a PR with a test case, where you specifically provide this certain parameters set?
