Squashed commit of the following:
apps/graphics/ft80x: Add support for accessing graphics ram. apps/examples/ft80x: Add more primitive graphics demos.
apps/examples/ft80x: Add a couple more demos of primitives. Use new ft80x_dl_create() to simplify.
apps/graphics/ft80x: Add ft80x_dl_create() which simplies writing of very simple display lists.

which will require 10's of kilobytes of memory (probably FLASH
