** Font Size ** 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. This was taken from [[http://emacs.stackexchange.com/questions/7583/transiently-adjust-text-size-in-mode-line-and-minibuffer][here]] but it has diverged significantly from the original.

"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."
