2.2 Command syntax
==================

Generally TeXdraw commands that take a single argument need a
terminating blank or newline after the argument.  Arguments that are
self-delimiting, such as coordinates within parentheses and text within
braces, do not need the terminating blank.  However, even when not
needed by the defining syntax of the command, blanks following command
arguments are allowed and ignored within the TeXdraw environment.

   On entering the TeXdraw environment, TeX is in internal vertical mode
(vertical mode inside a '\vbox').  In this mode, spaces can be placed
freely between commands.  However, any other extraneous input that
generates output that is not part of the TeXdraw environment is
disallowed.

   Blank lines are interpreted as paragraph breaks, equivalent to a
'\par' command.  The TeXdraw macro '\centertexdraw' is defined with the
'\long' attribute to allow '\par' commands and blank lines to be
interspersed between TeXdraw commands.  The '\btexdraw' and '\etexdraw'
commands also allow '\par' command and blank lines to be included.
