Description (last modified by )
The object of this ticket is to allow an optional argument "alpha" to set the transparency / opacity for contour_plot, like it exists for other types of plots.
An initial patch enables an 'opacity' argument to the contour_plot function. It should be renamed 'alpha' for consistency with its name elsewhere.
Doctests need to be added, and a few examples need to be written.

Comments from David Sanders on sage-support:
Firstly, with this code it seems not to be possible to make a region_plot *without* specifying opacity -- it looks like a default argument is missing somewhere.
