- Convert set_char to 8 byte bitmap.
- Reset ccmode on clear. Add a custom character cache to avoid unnecessary
updates of custom characters because of the reset.
- Add support for bignum.
- Remove the FB_modified flag, it did never work. Instead add a backing store
buffer to compare against. Remove the 40ms block of updates, this was a
no-op as well. However, pause 40ms after sending a complete screen update.
The display I have requires this to recognize the following cursor updates.
- Do not treat frame buffer as string. Always use memcpy, memcmp, and memset.
- Remove the changelog. This should be read from SCM.
- Remove contact info as T. Riewe has left Pyramid.
- Pass through indent, preserving 4 space indention.
