1. Remove connection type header files and put prototypes locally and in glcd-drivers.h. Don't fall into the pitfall of too many header files again. 2. Create a separate frame buffer structure (this allows easier re-use of the frame buffer functions). 3. Add a function to retrieve pixel values from framebuffer. 4. Add the 'serdisplib' connection type. 5. Support display width that are not a multiple of 8 (e.g. 122x32).
