Writing a plugin for debug mode?

AndroidStudio has this nice functionality where if you're debugging and you encounter a `Bitmap` object, it shows a "Show bitmap" link that actually gathers the image pixels (from the Android device) and shows them on the screen.

I want similar functionality for the OpenCV library for the `cv::Mat` object. Is there a way I can use the plugin infrastructure to do this? Looking this up is hard since most of the results show me how to debug a plugin... not how to write a debug mode plugin.
