/* NOTE for drivers:

|
The build-in DrawPixel(Fast), DrawCBR and ClearWindow have optimized for 1 bit
|
|
and 4 bits grayscale screen depth and 8, 16, 24 color. For any other type of screen,
|
|
DrawCBR and ClearWindow default to use DrawPixel, which is very sub-optimal. For
|
|
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
