template drawLinesAndMarkersLegend misleading doc

[doutriaux1]

the

import vcs
x=vcs.init()
t=vcs.createtemplate()
t.drawLinesAndMarkersLegend(x,["red","blue","green"], ["solid","dash","dot"],[1,4,8],["blue","green","red"], ["cross","square","dot"],[3,4,5],["sample A","type B","thing C"],True)

fails
the bg=True keyword seems to make it fail (i think it's because was rendered previously)

@doutriaux1 Which version of the docs is this from? My current version, the doc has this example
(The tedious declaration of lists is because the pdf formatting looks bad if those code examples go over 80 characters to a line):

>>> x = vcs.init()
>>> t = vcs.createtemplate()
>>> l_colors=["red","blue","green"]
>>> l_types=["solid","dash","dot"]
>>> l_widths=[1,4,8]
>>> m_colors=["blue","green","red"]
>>> m_types=["cross","square","dot"]
>>> m_sizes=[3,4,5]
>>> strings=["sample A","type B","thing C"]
>>> scratch=[True,False,True]
>>> t.drawLinesAndMarkersLegend(x, l_colors, l_types, l_widths,
...     m_colors, m_types, m_sizes, strings, scratch)
>>> x.png("sample")

My report doesn't indicate that there was an error with that test, so I think this issue will be resolved as soon as #114 is reviewed and merged.

good. @chaosphere2112 is reviewing this right now.
