Display large character for presentation
Presentation mode is a global minor mode to zoom characters.
This mode applies the effect of `text-scale-mode' to all buffers.
This feature help you to present Emacs edit / operation to the audience
in front of the screen.
## How to use
1. Execute `M-x presentation-mode' to start the presentation.
2. Adjust scale size by `C-x C-+' or `C-x C--'
See https://www.gnu.org/software/emacs/manual/html_node/emacs/Text-Scale.html
3. After the presentation, execute `M-x presentation-mode` again.
4. And then execute `M-x presentation-mode` again, the last scale will be reproduced.
5. If you want to persistize its size as the default size of presentation-mode
after restarting Emacs, set `presentation-default-text-scale`.
## Notice
### Not for "persistent font size change"
It is well known that how to change the font size of Emacs in GUI is difficult.
However, this mode is *NOT* intended for permanent font size change.

### Org Tree Slide / org-present
These packages are simple presentations using org-mode.
By using these with org-babel, it may be possible to perform live coding of
arbitrary languages.
