U8glib has several layers. Each layer is implemented with a callback function.
This callback function handels the messages for the layer.
The topmost level is the display layer. It includes the following messages:
U8X8_MSG_DISPLAY_SETUP_MEMORY no communicaation with the display, setup memory ony
U8X8_MSG_DISPLAY_INIT
U8X8_MSG_DISPLAY_SET_FLIP_MODE
U8X8_MSG_DISPLAY_SET_POWER_SAVE
U8X8_MSG_DISPLAY_SET_CONTRAST
U8X8_MSG_DISPLAY_DRAW_TILE
A display driver may decided to breakdown these messages to a lower level interface or
implement this functionality directly.
One layer is the Command/Arg/Data interface. It can be used by the display layer
to communicate with the display hardware.
This layer only deals with data, commands and arguments. D/C line is unknown.
U8X8_MSG_CAD_INIT
U8X8_MSG_CAD_SET_I2C_ADR (obsolete)
U8X8_MSG_CAD_SET_DEVICE (obsolete)
U8X8_MSG_CAD_START_TRANSFER
U8X8_MSG_CAD_SEND_CMD
U8X8_MSG_CAD_SEND_ARG
U8X8_MSG_CAD_SEND_DATA
U8X8_MSG_CAD_END_TRANSFER
The byte interface is there to send 1 byte (8 bits) to the display hardware.
This layer depends on the hardware of a microcontroller, if a specific hardware
should be used (I2C or SPI).
If this interface is implemented via software, it may use the GPIO level for sending
bytes.

One tile has exactly 8 bytes (8x8 pixel monochrome bitmap).
The lowest bit of the first byte is the upper left corner
The highest bit of the first byte is the lower left corner
The lowest bit of the last byte is the upper right corner
The highest bit of the last byte is the lower left corner
"tile_ptr" is the address of a memory area, which contains
one or more tiles. "cnt" will contain the exact number of
tiles in the memory areay. The size of the memory area is 8*cnt;
Multiple tiles in the memory area form a horizontal sequence, this
means the first tile is drawn at x_pos/y_pos, the second tile is drawn
at x_pos+1/y_pos, third at x_pos+2/y_pos.
"arg_int" tells how often the tile sequence should be repeated:
For example if "cnt" is two and tile_ptr points to tiles A and B,
then for arg_int = 3, the following tile sequence will be drawn:
ABABAB. Totally, cnt*arg_int tiles will be drawn.
