The idea is for shift-down-mouse-1 to pop up a context menu something
like this:

 Increase Text Size
 Decrease Text Size
 Change Buffer Font
 Restore Default Text Size

The operations in this menu would affect the text in the current buffer
only, via the face-remapping code.  The "Restore Default Text Size" item
would simply remove the face remapping.

With GTK/Fontconfig, the "Change Buffer Font" item pops up a GTK font
dialog to choose the font for the current buffer.  On Win32, it pops up
a Windows font dialog for the same purpose.  Otherwise, it would be a
submenu containing the old mouse-select-font choices.
