tuxtxt: fix display with scaling FB, use hw accel if available

Browse Source 
* Use a separate framebuffer and backbuffer on SPARK (the framebuffer
  is not big enough to have both buffers in it).
* make tuxtxt work correctly with scaling FB (1080 full-HD modes)
* improve performance by using the blitter to copy from back- to frame
  buffer if available (spark)
