+ * The themeEngine class is not instantiated directly.
+ * When a plot is initialized, the current plot options are scanned
+ * an a default theme named "Default" is created. This theme is

+ * is always available.
+ *
+ * A theme is a simple javascript object with styling parameters for

+ * JavaScript printf/sprintf functions.
+ *
+ * This code has been adapted from the publicly available sprintf methods
+ * by Ash Searle. His original header follows:
+ *
+ * This code is unrestricted: you are free to use it however you like.
+ *
+ * The functions should work as expected, performing left or right alignment,
+ * truncating strings, outputting numbers with a required precision etc.
+ *
+ * For complex cases, these functions follow the Perl implementations of
+ * (s)printf, allowing arguments to be passed out-of-order, and to set the
+ * precision or length of the output based on arguments instead of fixed
+ * numbers.
+ *
+ * See http://perldoc.perl.org/functions/sprintf.html for more information.
+ *
+ * Implemented:
+ * - zero and space-padding
+ * - right and left-alignment,
+ * - base X prefix (binary, octal and hex)
+ * - positive number prefix
+ * - (minimum) width
+ * - precision / truncation / maximum width
+ * - out of order arguments
+ *
+ * Not implemented (yet):
+ * - vector flag
+ * - size (bytes, words, long-words etc.)
+ *
+ * Will not implement:
+ * - %n or %p (no pass-by-reference in JavaScript)
+ *
+ * @version 2007.04.27
