Usually I have two windows vertical split layout when using Emacs. I'm curious is it possible to change default font size for one of them?
Typically, I use 14 points font height with 80 columns limit, when windows have same width this gives no line wrapping. But I've found bigger font size is better for eyes and eases viewing perception, however if windows have equal width the lines become too long and wrapping appears.
So the idea is to have one wide (major) window with bigger font size, and another window being narrowed with smaller font-size. I know I can set up font per buffer, but this is not what I need, e.g. I want same buffer being rendered with bigger font when visited in major window and with smaller font when visited in secondary window.
On a screenshot above there are major window is outlined with green colour and secondary window is outlined with blue one. For example I want to have 18pt font size for major window and 12pt font size for blue window.
