 Control Vim editor font size with keyboard or mouse.

+==============================================================================
+Remarks.
+
 This plugin is for GUI only.
 
+Currently, this plugin olny works for fonts, that are defined as a typeface 
+name AND the size. For example: >
+
+    set guifont=DejaVu\ Sans\ Mono\ 12
+    set guifont=Consolas:h10:cEASTEUROPE
+    set guifont=Monaco:h11
+
+Putting only name will not work at all, since guessing default font size for 
+all of the operating system can be difficult.
+
+For Linux, *BSD or other unix-like system it will be assumed, that graphical 
+environment is an X11 system. Wayland, or other non-X solutions will be added 
+as they emerged, however wayland-x11 driver may work OOTB.
