Re: latex mode, nexted subscripts are unreadable

Hi Tim,

Thanks for the report.

    the nested suscripts are visible, but are still too tiny for comfort.
    And they're not clearly visible - the gray letters end up with most of
    the pixels light gray and a few of them darker.

Unfortunately neither I nor Juri were able to reproduce this on our
(non-Windows) systems.  

Is there an Emacs developer who works on Windows who could look into this?

    Is there a way to set a minimum font size for suscripts?

Looking at tex-mode.el, it seems that faces named `subscript' and
`superscript' are used for this.  By default, they are defined like this
(both are just the same except for the name):

    (defface subscript
      '((t :height 0.8)) ;; :raise -0.3
      "Face used for subscripts."
      :group 'tex)

The :height is presumably what makes it proportional to the next "level"
up.  So perhaps it would work to override these definitions by changing
those faces -- using customize is probably easiest -- to use an absolute
font size.

Best,
Karl
