IFrame fix in save_fig

[amritbhat786]

Hi Luca, Were you able to find a solution to display pdfs using the Iframe class in the display module of IPython? I am trying out the same, but the pdf file is not loaded if a file path is given as value for the src parameter of Iframe. It only works in case of urls as the value for the parameter.

PS: Also there is a function called display_pdf which can be used to display pdf from a file, although in that case it seems like in the case of customization a pdf object will have to be formed. Please let me know if you were able to find a solution.
