intro screen in m2tk lib with glcd

Always place graphics commands within the firstPage/nextPage loop.
u8g_Begin is not required.

void introScreen() {    
    u8g.firstPage();  
    do {
        //u8g.drawBitmapP( 0, 0, 1, 8, rook_bitmap); //show image
        u8g.drawRFrame(5, 10, 40, 30, 10);
        u8g.setFont(u8g_font_unifont);
        u8g.drawStr( 0, 20, "AAAAAAAAA");
    } while( u8g.nextPage() )
   delay(5000);                          
}
