There's not a huge amount of difference between the possible implementations, the harder bit is
compositing the different windows. I think that this should ideally be done in OpenGL with the
updates asynchronous and synced to a maximum of the refresh rate of the monitor, but it's probably
easier to fetch the data to a didsection.
