[Eric] change Eric background to an image

[Dmitrey]

Hello,
first of all thank you for the excellent Python IDE once again.

I would like to change background in editor widget and python shell from 
white color to an image like the ones from

Can it be done in current Eric version? If not, could you consider 
adding this into future Eric releases?

Regards, Dmitrey.
