Detailed Description

objects.

Fig(obj, obj, obj..., trans=function)

obj     optional list    a list of drawing primatives
trans   default=None     a coordinate transformation function

>>> fig = Fig(Line(0,0,1,1), Rect(0.2,0.2,0.8,0.8), trans="2*x, 2*y")
>>> print fig.SVG().xml()
<g>
    <path d='M0 0L2 2' />
    <path d='M0.4 0.4L1.6 0.4ZL1.6 1.6ZL0.4 1.6ZL0.4 0.4ZZ' />
</g>
>>> print Fig(fig, trans="x/2., y/2.").SVG().xml()
<g>
    <path d='M0 0L1 1' />
    <path d='M0.2 0.2L0.8 0.2ZL0.8 0.8ZL0.2 0.8ZL0.2 0.2ZZ' />
