/**************************************************************************
 *
 *	History:
 *
 *	15.06.2002	added bframes options
 *	21.04.2002	fixed custom matrix support, tried to get dll size down
 *	17.04.2002	re-enabled lumi masking in 1st pass
 *	15.04.2002	updated cbr support
 *	07.04.2002	min keyframe interval checkbox
 *				2-pass max bitrate and overflow customization
 *	04.04.2002	interlacing support
 *				hinted ME support
 *	24.03.2002	daniel smith <danielsmith@astroboymail.com>
 *				added Foxer's new CBR engine
 *				- cbr_buffer is being used as reaction delay (quick hack)
 *	23.03.2002	daniel smith <danielsmith@astroboymail.com>
 *				added load defaults button
 *				merged foxer's alternative 2-pass code (2-pass alt tab)
 *				added proper tooltips
 *				moved registry data into reg_ints/reg_strs arrays
 *				added DEBUGERR output on errors instead of returning
 *	16.03.2002	daniel smith <danielsmith@astroboymail.com>
 *				rewrote/restructured most of file
 *				added tooltips (kind of - dirty message hook method)
 *				split tabs into a main dialog / advanced prop sheet
 *				advanced controls are now enabled/disabled by mode
 *				added modulated quantization, DX50 fourcc
 *	11.03.2002  Min Chen <chenm001@163.com>
 *              now get Core Version use xvid_init()
 *	05.03.2002  Min Chen <chenm001@163.com>
 *				Add Core version display to about box
 *	01.12.2001	inital version; (c)2001 peter ross <pross@xvid.org>
