/*
  1. if define USE_DRAW_BUF, lvgl will alloc draw buffer instead of sharing framebuffer
  2. draw with/height can be different with framebuffer
  3. draw buffer can be scaled/rotated and output to framebuffer
  4. draw buffer can be rotated 0/90/180/270 degree
     (1) the default rotation of your display when it is initialized can be using the rotated flag.
         the avaliable options are LV_DISP_ROT_NONE,LV_DISP_ROT_90,LV_DISP_ROT_180 or LV_DISP_ROT_270
     (2) display rotaiton can alse be changed at runtime using lv_disp_set_roation(disp, rot) API.
