+  By default, when you split a window, Emacs gives each of the
+resulting windows dimensions that are an integral multiple of the
+default font size of the frame.  That might subdivide the screen
+estate unevenly between the resulting windows.  If you set the
+variable @code{window-resize-pixelwise} to a non-@code{nil} value,

+character size, at least one window may get resized pixelwise even if
+this option is @code{nil}.
