Modify pin for TFT_LCD with 'Adafruit_GFX.h'

Hello all,

I have an Arduino Mega 2560 and a Kuman's LCD (420*380).

I would change the pin connexion beetwen the LCD and the mega.

Initially, we have:

LCD_D0 -> pin 8 LCD_D1 -> pin 9 LCD_D2 -> pin 2 LCD_D3 -> pin 3 LCD_D4 -> pin 4 LCD_D5 -> pin 5 LCD_D6 -> pin 6 LCD_D7 -> pin 7

And I would have:

LCD_D0 -> pin 22 LCD_D1 -> pin 23 LCD_D2 -> pin 24 LCD_D3 -> pin 25 LCD_D4 -> pin 26 LCD_D5 -> pin 27 LCD_D6 -> pin 28 LCD_D7 -> pin 29

I tried to use differents library but nothing works. In the Adafruit_GFX.h there is nothing which define those pins.

Thank you for all in advance for any help to solve my problem.
