al_legend shows the correct font size in GDL with a minor change in the call to cgText

[ChristerSandin]

Using al_legend in GDL, I find that al_legend produces legend text with the correct font size if in the three occurrences of calls to cgText, the keyword SIZE=charsize is replaced with CHARSIZE=charsize, as in:

cgText,x,y,items[i],width=width,/norm,color=textcolors[i],charsize=charsize, $
            align=xalign,charthick=charthick,font=font
