The point of this is to make drivers based on Adafruit_GFX_AS compatible with Adafruit_GFX,
without breaking existing code written for Adafruit_GFX_AS.

readcommand8() toggles _sclk, but when using hwSPI it's set to 0, ie. it's toggling GPIO0, which it obviously shouldn't be doing. Also, when SPI-transactions had been enabled the SPI-bus speed was set to only 8MHz -- now we set it to 36MHz on STM32F1.
This way one knows if he is using the old or STM library by looking at
the include line, while the sketch should compile file as the functions
are named the same. I believe this is the best compromise.
