* InitVideo() and GRRLIB_Start() merge into GRRLIB_Init().
* add GRRLIB_PtInRect, GRRLIB_RectInRect and GRRLIB_RectOnRect.
* add GRRLIB_Exit to free the memory allocated by GRRLIB
* GRRLIB_GetPixelFromtexImg and GRRLIB_SetPixelTotexImg ////////////////////////// BUGGED DO NOT USE !!!
* add GRRLIB_Exit to free the memory allocated by GRRLIB
have a look at the sample code to see how all this work ;)
