Version-Date---Author-Explanation
----------------------------------------------------------------------
2.00    010402 RS     a) LCD_GetDevCaps removed from driver
                         (now LCD.c)
1.30c   000529 JE     a) Interface changed
1.30b   000428 RS     a) DIB class eliminated
                      b) Internal cleanups, support for high color
1.30a   000417 RS     a) Major cleanup in DIB class
1.30    000309 RS     a) Interface change for emWIn V1.30
                         (LCD_L0_SetLUTEntry, LCD_GetDevCap)
1.10a   000121 RS     a) RECTHEIGHT, RECTWIDTH modified in order to
                         fix bug which would at some time prevent
												 displaying the first line of the display.
1.10.00 000110 RS     a) Modifications in order to make it easy to
                         implement driver in any windows program

                         LCD_MAX_LOG_COLORS
1.04.01 991018 RS     a) Support for LCD_FIXEDPALETTE added
                         with Anitaliasing enabled
1.04.00 991013 JE/RS  a) Support for LCD_FIXEDPALETTE added
                      b) Driver now accepts the same LCDConf.h as
											   the embedded system
											c) Bugfix for ..
1.02.02 990831 RS     a) Small optimization added for 16-color bitmaps
1.02.01 990726 RS     a) Transparency support for 16-color bitmpas
                         added
1.02.00 990212 RS     a) New interface version 1.02 supported
1.00    990118 RS     First release
