+% 7 - There were several problems when doing a global change of color
+% outside the "slide"environment (using the \color{ColorName} macro
+% of the `color' package) if this change was not done globally
+% (that is to say before the "\begin{document}") but inside the document,
+% for a part of the slides.
+% These problems can be seen specially for screen presentations,
+% when we want to use a dark background, so a light foreground color
+% for the text.
+% First, the header (defining for instance with the `fancyhdr' package)
+% changed of color one slide later and was restored one slide later too
+% if the change of the color was mas inside a group for some slides,
+% and second, the black color was forced by the footer.
+% We solve the first problem by usage of the same technique than the one
+% used by Seminar for global changes based on \special macros and made
+% before the "\begin{document}". We save the \specials in the
+% \saved@specials box and insert it at the beginning of the \@slidebox box
+% with the \insert@specials macro, as for the first slide.
+% And we solve the second problem by suppression of the command in the
+% hook which force the black color (defined in the `semcolor' package).

+% 7 - To vertically correctly center the footer, if defined
+% (this is mainly visible when using the `fancyhdr' package, and specially
+% when a footer rule line is defined)
+% (reported by Denis Girou (CNRS/IDRIS) - <Denis.Girou@idris.fr> - April 1998)
+
+% 8 - Add-on to allow "full screen" backgrounds.
+% Seminar originally support only partial backgrounds, which doesn't cover
+% the full page but only the place of the text. It cannot be easily
+% modified, as there are dependancies between the header and the text.
+% So, we choose to define new macros \SeminarNewSlideFrameBackground
+% and \SeminarSlideFrameBackground to manage the full screen backgrounds,
+% designed on the model of the \newslideframe and \slideframe ones.
