Michael Hope 51dddbdc17 lcd: use writePattern for faster erases and lines. 
The ESP8266 SPI implementation has a 'writePattern' function that
writes a repeating sequence (in this case a solid colour) to the SPI
port.  This fills up the FIFO and increases the bus utilisation.

Using this for clearing the screen cuts the demo run time from 4721 ms
to 3601 ms.  Also using this for the fast lines cuts the run time to
3424 ms.

Michael Hope a56ebc5151 lcd: send 16 bits at a time to speed up drawing. 
If the hardware supports it, send 16 bits at a time.  This is
worthwhile on chips that have a FIFO like the ESP8266 as it cuts the
demo render time from 6083 ms to 4721 ms.

Michael Hope 999f5ff29d lcd: add support for the ESP8266. 
Refactor the chip and data pins to generic functions.  Add support for
controlling CS and RS via the standard digitalWrite() functions.  Add
support for hardware SPI only devices.

wa5znu 0aa5b9bda2 In spitftbitmap example sketch, close the SD card file, so that 
people who follow the example and use copy and paste will wind
up with code that works more than once.
