** Font Size
This was taken from [[http://emacs.stackexchange.com/questions/7583/transiently-adjust-text-size-in-mode-line-and-minibuffer][here]]. It is primarily invoked from a hydra defined below. It would be cool if it got the default font size from whatever the default font was but it does not currently do that.

(setq imalison:default-font-size-pt 14)
(defun imalison:font-size-adj (&optional arg)
"The default C-x C-0/-/= bindings do an excellent job of font resizing.
They, though, do not change the font sizes for the text outside the buffer,
example in mode-line. Below function changes the font size in those areas too.
M-<NUM> M-x imalison:font-size-adj increases font size by NUM points if NUM is +ve,
decreases font size by NUM points if NUM is -ve
resets font size if NUM is 0."

;; The internal font size value is 10x the font size in points unit.
