[l2h] Improved images in LaTeX2html

[Sergej V. Znamenskij]

Dear latex2html friends!

I have done some useful (AFAICS) changes to latex2html code: 
   * dvips+ImageMagick is replaced to dvipnd, translation became very 
   fast if type1 fonts are installed;
   * Formula positioning was corrected: try
	http://u.pereslavl.ru/~googlecode/explorer
   or
	http://u.pereslavl.ru/~googlecode/mozilla
   depending on the browser you use to see difference in output;
   * Black boxes and rules will never mark formula with wrong LaTeX box 
   size information;
   * You can use non-white background now;
   * Cyrillic encodings koi8-r and cp1251 became also fully supported   
   now.
The screen html appearance was rather well tested on Debian linux. 

Debian users with tetex, netpbm and dvipng installed can test new
features: unpack in any place 
http://www.botik.ru/~znamensk/sbornik/latex2html.zip
or the same
ftp://ftp.botik.ru/rented/znamensk/www/sbornik/latex2html.zip
and run executable script in subdirectory test (no configuration needed)

I'd like to make new features available for public usage, but do not
know the right way to go. I probably have no resources to keep supported
printing, thumbnails, or to test dos or windows distributions.  

Help, please! Any suggestions will be appreciated.

Yours,
Sergej Znamenskij
