//! Draws a centered string.

//! \param pContext is a pointer to the drawing context to use.
//! \param pcString is a pointer to the string to be drawn.
//! \param lLength is the number of characters from the string that should be
//! drawn on the screen.
//! \param lX is the X coordinate of the center of the string position on the
//! screen.
//! \param lY is the Y coordinate of the center of the string position on the
//! screen.
//! \param bOpaque is \b true if the background of each character should be
//! drawn and \b false if it should not (leaving the background as is).
//!
//! This function draws a string of test on the screen centered upon the
//! provided position.  The \e lLength parameter allows a portion of the
//! string to be examined without having to insert a NULL character at the
//! stopping point (which would not be possible if the string was located in
//! flash); specifying a length of -1 will cause the entire string to be
//! rendered (subject to clipping).
//!
//! \return None.

//! This function determines the maximum width of a character in a string.  The
