Extension for control SSD1306 OLED display 128×64.

argument is the color of pixel on the OLED display. The true means that the pixel will be on, false means that the pixel will be off.

and arguments are the x and y positions. Point 0,0 is in the upper left corner of the display. The display is 128 pixels wide (x) and 64 pixels high (y). This means that can be from 0 to 127 and can be from 0 to 63.

argument sets whether pixel inversion is used instead of pixel redrawing.
