jweb can't output a matrix – help with workaround?

I am trying to overlay drawings onto a website. I need the users to be able to navigate freely around the internet, so I need to use the jweb object, not just images of the website. However, there doesn’t appear to be any way go get jweb to output a matrix, so I can’t get it to play nice with the jit.lcd object that I am using to create the drawings.

Is there a way I can work around this issue?
