/******************************************************************************* JMatrixCtrl.h To use this class, simply create it and call AddTextLine() for each line of text to display. You can specify a page break with a line that looks like "\x01 T", where T is a positive integer specifying how long to wait before starting on the next page. The default behavior is as close to the actual Matrix credits as I could manager. You can obtain a range of different effects with the following settings: SetIntervals(const int intro, const int restart) Specifies how many seconds to wait before displaying the first page, and how long to wait before restarting after all pages have been displayed. SetCursor(const BOOL show, const BOOL solid) With no cursor, each line is drawn all at once and then begins to phase in. Otherwise, the text appears as the cursor moves. If the cursor is not solid, it is a randomly changing character. SetMaxPhaseCount(const int maxCount) Specifies the maximum number of iterations before a character is forced to the correct value. A character stops changing when it hits the correct value or exceeds maxCount. Specify a huge value to let the characters phase in "naturally". Specify zero to simply display the text. AllowEuropeanChars(const BOOL allow) The disadvantage of allowing European characters is that it takes *much* longer for the text to phase in when SetMaxPhaseCount() is called with a very large value.
