I put in a brief inquiry at UDig to see how they handle raster rendering. I wanted to forward their response, although I don't know how much help it will be.

Our rendering API has a method that takes a Graphics2D so that can be backed onto a ImageWriter that directly writes to a file if necessary. Or a printer (which it was originally designed for). 2. We stream features in but don't keep them around 3. We use JAI to efficiently read Imagery data from disk while keeping a smaller in-memory footprint.
