tv_ZDot x y button pressure
Draws a dot with the current brush or custom brush in the current image in the current layer. The x and y arguments are the coordinates at which the dot is to be drawn. The button argument indicates if the pixel should be drawn as it would if the mouse left button (value 0) or right button (value 1) were pressed. The pressure argument represents the pressure used for the dot. Remember that this function does not necessarily draw only one pixel, but a dot with the brush; if the selected brush is very large, the result will be a very large dot.
