(1) corrected SPI com by adding a very small wait (8 us) after changing state of A0 pin. Redef DOGMLCD_TIME if you need to change value.

(2) Added off screen managment with methods AttachScreen, DetachScreen and Paste.

- Attach your screen buffer (char [1024] )

- Use Doggys\ drawing functions to prepare it

- Detach screen

- Anytime, use Paste to combine with work screen by raster commands poke,wipe or inv.
