% \section{Driver files}
%
% This file implements some of the currently supported drivers.
% If the driver you use is not in this list then a `.def' file
% may be distributed with This graphics bundle,
% or may be distributed with your driver.
%
% If not, send us some details of the driver's |\special| syntax, and
% we will try to produce a suitable file.
%
% Note that some of these files are for drivers to which we have no
% access, so they are untested. Please send any corrections to the
% latexbugs address.

% \section{Colour}
%
% Most of the drivers that support colour use one of three methods.
% \begin{itemize}
% \item color1: `dvips' style colour specials.
% \item color2: `textures' style colour specials.
% \item color3: Colour implemented via literal PostScript specials.
% \item color4: Colour implemented by specials that only support RGB,
%               i.e., Red Green Blue specified as integers in the range
%               0--255. Other models converted to this within \TeX.
% \end{itemize}
% Some drivers do not use any of these modules and have their own code.
% Note that drivers using the `color3' code can not fully support the
% \LaTeX\ colour commands.
