/* NOTE for drivers:

The build-in DrawPixel(Fast), DrawCBR and ClearWindow are optimized for 1 bit
|
|
and 4 bits screen depth. For any other type of screen, DrawCBR and ClearWindow
|
|
default to use DrawPixel, which is very sub-optimal. For such other depth, you
|
|
must supply the DrawPixelFast. The built-in 1 bit depth function are only for
|
|
screen with vertical framing (1 byte = 8 lines). For example SSD1326 in
|
|
monochrome mode is not such type of screen, SH1106 and SSD1306 are
