drawLegend - when Description contains "\n"
Maybe this was never supposed to be allowed, but in Version 1.2x you could use a wordwrap with "\n" to get long Descriptions fit into the legend - so they expand only to y-Axis.
In Version 2.0.4. This will not work.
I have very long descriptions, that will never fit into the Legend if they don't wrap with a "\n".
So I made a small change to the function
drawLegend() that will fullfill my requirement, but it is not perfect (see later)
Changes will affect only LEGEND_VERTICAL:
"Align"=>TEXT_ALIGN_TOPLEFT
Coordinates will be dependant from FontSize and number of "\n" in the Description.
Sad, i could not made it work perfect for all fontsizes. The Scalefactor (1.2) is only a dirty-hack
I hope someone else may find a better Solution.
